    Initially, two plates were missing but customer service was eventually able to handle my concern and sent out the missing plates. Overall good product.

    Amazing weights.
    Great quality, handle grips very comfortably.
    Easy to change the weights and transfere to long bar if required.
    Highly recommended and worth the money.

    My husband is happy about the weights. Just the handles are slightly uncomfortable, so 1 star deduction. He uses sports gloves now so it’s all good.

    I love these dumbbells and the bar they give a great workout and they’re easy to store away. I’m very happy with these. Over the last month my arms have definitely got bigger.

    Good results!

    Got them for my soon to be teenage son, he loves them.
    Did quite a bit of research, and chose these for two main reasons;
    1. Best per kg set available without going cheap and nasty.
    2. Best weight range available.

    My first time buying dumbbells for use at home and I am very pleased with the quality of these dumbbells. They are the correct weights, the barbell bar which comes with it is also very solid and can withstand the weight of the dumbbells attached to it. The locks at the end of the dumbbells screw on perfectly and do not come loose. The only reason why I gave this 4/5 was because one of my dumbbell bars was uneven however everything else about this set was perfect and this is a very high quality set. I think that the only downside to this set is that the handles of the dumbbells are a bit rough and so I bought a pair of weightlifting gloves to protect my palms from burns and blisters.

    I’d highly recommend obtaining this solid piece of kit for any home gym! I’ve used countless dumbbells before, but this one is the decider for me…

    The weight plates are small cast iron sets which are very small but weighs heavy. The spinlocks are durable and locks in real tight so it doesn’t budge at all!

    Furthermore, the bars themselves look and feel amazing! It provides for a good & tight grip during a hard workout.

    However, the weight plate’s paint is flaky, and bits come off during moving them around etc. Also, the rubber washers always drop out, I’d recommend the developers super gluing them to the spinlocks themselves for a better overall experience from a user’s perspective. But that’s the only downside, besides that, it’s perfekt guys!

    This is a flexible option, to load or off load. Rather simple to put together. Very well packed. Price is worth it.

    Never written many reviews but I’ll try to be honest here as these have impressed me but it’s not just about praise…

    So the cons that aren’t entirely clear in the description:

    The barbell is a joining tube that will join the two dumbell bars together. Since the the rubber grip are fixed in place you’ll be stuck with a single wide grip. Also to load the maximum weight on the barbell you’ll have to load either side of each grip which means certain exercises the inner weights will affect the angle you can grip the bar on.

    Here’s the positives though:

    For what it offers I’ve been very, very impressed, everything I’ve found a problem with other weights like this just isn’t here. The dumbell bars aren’t over length, they offer just enough for all the weight plates fitted and the screw. Some dumbell bars are simply far too long to be comfortable.

    The bars themselves are all chromed steel of a hollow but thick walled construction. Good stuff as many are silver painted plastic and break in a week. The end caps and the connecting bar all fit tightly with a low tolerance and can be easily screwd tight enough that nothing moves or wobbles. The end caps have a rubber fitting that prevents scratching the plates and also offers a snug fit, you shouldn’t find them coming loose unless you want them too.

    The overall packaging was also neat and efficient. So much in fact I thought the courier had missed a second box but on opening there it all was.

    It’s a bit more than the cheapest equivalents on Amazon but all the cheaper ones have some form of issue that these simply don’t. My advice with these as my third weight set is go for these for the extra money but also don’t assume they’re the best they can possibly be. Many are more expensive for a reason but I also don’t think you’ll get better on Amazon cheaper.

    It’s a good set for beginners, but as you progress through your level of strength, you will be able to buy another set, so that you have more of the larger weights. This will also mean you can leave a set of handles as dumbbells, and another as a barbell.

    When in barbell setup, there is a slightly play in the screw fixture, but this has never been of concern as the handles screw into the barbell bar a decent way, so this is definitely not coming loose.

    Arrived well packaged and without flaws.
    Great design and top quality.
    Made from cast iron feel resistant and long lasting.
    Comes with different set of weights, from 0.5kg to 1.5 and 2.5kg, four of each.
    The bar supports the weight perfectly and can be adjusted to be longer and support more weight.
    The screws hold the weights tight and have no rough edges.
    Its a great versatile kit, perfect for exercise at home, i just find it a little pricey.

  25. Rick Pearson says:

    This is a nice set of weights, that generally feel of outstanding quality – with a couple of points that let them down a little.

    Impressive is the small box it came in, I have used my signature measuring item, a drinks coaster, to demonstrate the size.

    The minor letdowns:
    The insides of the weights are not as smooth as the outside and I ended up with a little metal splinter. It made it hard to get them out that way, and I wouldn’t really lift them by the inside. I did think about turning the box upside down and cutting the box open. Of course – do this carefully!
    Even though the cast iron is stunning, there are places with ridges – I don’t know if it’s just this set but they didn’t feel to the standard that I believe the manufacturer would want. A little picky yes, but they are 70
    When screwing one of the dumbbell pieces into the middle tube to make a barbell – wow, the squeaking noise. I hope that sound soon stops. It might not bother you, bothers me. The other side of the same bell didn’t do it.
    The grip, I am personally not a fan of. Although I understand from the description there’s a specific reason around the grip, etc. This will very much be a matter of preference.

    There’s no questioning this is a quality and innovative product. And if those few niggles that just stop it from feeling like a really well-rounded product were addressed, this – even with the cost – would be an easy five-star product.

    In my view, it’s just shy of that, even though I think these are excellent.

    A respectable FOUR stars from me. (8 1/2 out of Ten)

    Convenient, innovative - but let down slightly by a couple of quality flaws.

    Can’t go wrong with cast iron dumbbell! Especially this set.

    These dumbbells are very good quality build, comfortable to grip & easy to put together.

    Black cast iron and black grip make this set look very appealing.

    I love the fact the dumbbells can be converted easily to do full bar squats, bench press, high pulls and your usual normal dumbbell exercises really inventive piece of kit here.

    Highly recommended for beginners and experts!

    Super quality dumbbells for many different type of exercises at a very good price point!

    Great set of weights you get 2 lots in one you can make it up into 2 dumbbells or 1 barbell.
    You get 3 different size weights 4 of each

    If making a var bell you have 3 poles 2 woth handle grips which are the 2 outer bars and one for the middle to join them which is a plain metal bar.
    They 3 bars just screw together then you add you required weights on each end and then there is a screw cap to keep the weights in place.

    The dumbbells can be made up using the 2 bars with handle grips on you just add the weights to each side of 5he handle then use the screw caps to keep the Wight in place
    Make sure you screw the cap on tight so the weights aren’t loose and move around.

    This is a very easy set to use so simple to put together basic but effective. Smaller weights to start off small and can build up to the larger weights in time.
    The grip on the handle is compdotable to hold none slip it’s all wipe clean I just use a damp cloth and a dry towel if needs a clean down after a work out.
    Breaks down small for easy storage when not in use.
    Great quality no complaints

    If you are a little short on space then this dumbbell set from Amonax could be ideal.
    The weights are made of cast iron, feel well made with no rough edges and are far better than the plastic ones. The dumbbell bars are made of stainless steel and have a nice rubberised grip on them which is comfortable to hold and also helps to prevent them from slipping in your hand. The weights are held on via stainless steel spinlock nuts, which feel pretty smooth when screwing them on and they also have a nice rubber washer, which helps to grip the side of the weight to prevent it unscrewing by itself.

    You also receive a handy little extension bar which has a screw thread at either end, allowing you to screw the dumbbells onto it, turning it into a set of bar bells.

    ***** In The Box *****

    2 x Dumbell bars
    1 x Extension Bar
    4 x 2.5KG weights
    4 x 1.25KG weights
    4 x 0.5 KG weights
    4 x Spin Locks

    ***** Conclusion *****

    I really like the design of this product from Amonax. We only have a small house, so being able to turn the dumbells into a barbell by simply adding a screw on extension is really handy and saves a lot of storage space.
    The bars and weights all seem to be of good quality and I like the non-slip grips.

    The description mentions that you get an included workout guide, but there was no paperwork or guide included in my box.

    I think value for money is pretty good for a cast iron set of weights, although I have noticed a couple of identical sets which also include a hard plastic storage case for a little less money and if I were buying a set, I would choose the one with the case over this.

    This set of 20kg weights is a perfect starting point for beginners looking to strengthen themselves at home. They come surprisingly well packaged for a set of weights, inside the iron plates protected in a hard foam packaging which protects everything in shipment. In the box you get 4 x 2.5kg plates, 4x 1.25kg plates, 4 x 0.5kg plates, 2 x dumbbell bars, 4x spin-lock collars and 1x chrome barbell connector. The cast iron plates feel of good quality and are painted nicely, they also have a shiny coating applied to them and feel a lot smoother to touch than my other plates.

    The dumbbell bars have grips attached to them that make them comfortable to hold, so you won’t need to buy a set of weightlifting gloves to use these (unless you want to). The barbell connector is a really smart addition, it lets you screw in the dumbbell bars and convert it into a barbell which I think is really innovative and great if you’re short on space. The only downside to this approach is that you are limited with how many plates you can put on the bar, but as a starter kit I’d say this wouldn’t be much of a concern. This barbell will let you put on all the plates and give you more workout choices for your routine rather than just using dumbbells alone.

    Overall, for a beginner this is an ideal set of weights, and once you get stronger and the weight starts becoming easy to lift you can easily order some 5kg plates since these are widely compatible. Thank you for reading my review, if you found it helpful let me know below!

    This set, whilst slightly pricier than a few other similar dumbbell kits is good quality, is well finished, look nice and are easy to use.
    The set arrives in a box packed with polystyrene. To get at the bars, you have to remove the 2.5 and 1.25 kg plates, then the polystyrene insert can be removed.
    The bars are chromed, with a hard rubber handle, which will keep the chill off, on cold mornings.
    The plates themselves are painted grey, and have a shiny coating (until chipped, I guess) which look smart; and are secured with collars which screw onto the bar ends – these are relatively slim, compared to other sets, but have a continuous thread to secure the weights – an inferior set that I have has a longer collar sleeve, which has fewer metal threads, but a piece of plastic tubing as a spacer; this is a nice detail where they have not cut material and manufacturing costs for safety.
    In use they’re solid – the plates do not move when secured.
    I tried the centre barbell attachment, which attaches to the dumbbell bar threads and secures with a grub screw – I’m not sure of how strong this would be if you added more weights, especially if you wanted to do heavier barbell work, but for the 20kg supplied they will be fine.
    In all, a good quality starter set.

    I was actually surprised that this package was so small when it arrived and had to check what I’d ordered before opening.

    This item is really well packaged and nicely presented. The weights are solid, not filled and the dumbell handles screw into a centre bar to create the bar bell which is a really good space saving idea.

    My package didn’t come with the user/workout guide and the dumbell handles could be more moulded for better comfort although they are anchored in the centre of the bar to avoid play in the weights and unbalancing during use.

    Other than that this appears to be a quality hard wearing product.

    This is a really good versatile set of weights, enabling a range of loading so many people can use them or you can work their way up to heavier weights.

    My husband used to have a lot of weights but he got rid of them some time ago because they took up so much room, but with these, they all can be easily dismantled and put back in the box when the workout is finished. He’s monopolised these since they’ve arrived!

    The weights are assembled into either a pair of dumbells or a barbell and weights are added or removed depending on the amount you want to lift, meaning they’re suitable for beginners or other members of the family (like me).
    The cast iron weights in the set are: 4 x 2.5kg, 4 x 1.25kg and 4 x 0.5kg. There’s 2 short bars, each with comfortable and non-slip cushioned grip pads and 4 collars to secure the weights.
    The short bars make the pair dumbells or you can screw on the extension in the middle of the two shorts which creates the barbell. There’s no slipping of the weights either. The whole lot can be taken apart quickly once finished and put back in the box- no storage nightmares! I think there was supposed to be a manual included with exercises but I can’t find it. It might be downloadable, but that makes little difference.

    Good quality, comfortable to hold and use. Really pleased.

    Very impressive set of dumbbells. You get 2 dumbbells with 10kg of weight on them (3 separate weights on each side so you can adjust the weight as necessary), and you get a weird joiner thing so you can change the 2 dumbbells into 1 barbell.

    The handgrips on them are a nice smooth plastic, not slippy but just stops your hands from scratching up while you are working with them. The locks on the end, to hold the weights on, secure quite firmly and don’t come loose while you are doing curls (something that has happened on other weights I have used in the past).

    Even the joiner bit seems solid, and once you have screwed it together it works perfectly adequately for a lightweight barbell. I can’t really see too many people using it, but it is a nice addition.

    Overall, I am very impressed with these weights, and for a relative lightweight like me this is all the weight I will need.

    These arrived well-packed in a single box (though using expanded polystyrene – not very green…), and are very easy to set up for whatever weight you need – there are 4 x 2.5kg, 4 x 1.25kg and 4 x 0.5kg, so can be put together in a very wide range of combinations.

    The locknuts are good, and cleverly include a rubber washer on the inner surface that grips against the weight disc when the locknut is tightened – this should prevent the nuts from loosening and is a more elegant solution to the issue that some I’ve seen.

    Size-wise, these are great – they are much more compact than the plastic coasted cement cheap weights I’ve had for years (see attached photo for a size comparison of the same 7.5kg weight!)

    The one aspect I’m slightly concerned about is the screw-on bar to convert from dumbbells to barbell. Although the thread fits securely, basic physics says that if you have weight further away from a potential point of weakness (a longer lever), the more the potential for failure. However, I suspect I’ll only ever be using these as dumbbells anyway.

    Good quality and a step up from cheap plastic-coated weights!

    Very pleased with the weights set so far.
    Build quality is great.
    Very well packaged. Arrived in the package as shown in the attached photos.
    The iron rod is adjustable and can be easily extended.
    Due to 3-pieces iron rod, weights can be attached in different rod length and combinations. So, the weight set is even suitable for beginners.

    Easy to switch weight amount on the rod. Came with 4 pieces of 2.5 kg, 4 pieces of 1.25 kg, 4 pieces of 0.5kg. Thus, a good combination of weights can be put on the rod based on our requirements.
    Great for exercise at home.
    Dumbells are not slippery. Easy to fit. Comfortable to use.

    The price of 80 GBP looks reasonable as the weight set is really of great quality.

    Overall, I am happy and will recommend.

    Golden Review Award: 6 From Our UsersIn the box you receive: 4 x 2.5kg plates, 4x 1.25kg plates, 4 x 0.5kg plates, 2 bars to make the dumbbells, 4 spinlocks to secure the weights on the dumbbells, and a dumbbell connector that turns the two dumbbells into a single unit – allowing you to use it similarly to a barbell.

    The weight plates are made from cast iron, which is an extremely hard iron and carbon alloy. This means it’s durable and the weights all look great. They are smooth with the amount of weight labelled on them. I haven’t had any issues with them chipping. Similarly, the dumbbell bars, connector bar and spinlocks all feel durable and well made.

    Putting everything together is simple. You grab a dumbbell handle, slide on the weights you want and then cap each end with a spinlock. In this configuration you can do barbell exercises such as shoulder presses or curls or lateral raises, etc. Then, should you wish to use your weights as a barbell, you simply screw the connector bar into one of the dumbbells and then screw the remaining dumbbell into the connector bar. The barbell is now set up and perfect for narrow or wide grip curls, raises, squats, rows, etc.

    The only real downside of this type of barbell is that certain grips won’t be available and because you have the weights around the shoulder area, you won’t be able to do certain exercises such as full range of motion presses as the plates will hit your chest early.

    Overall, this is a really good quality and versatile set. By having the connector bar, you have both the ability to do single arm exercises and two arm exercises, which opens things up considerably.

    Great dumbbell and barbell combo

    Extremely fast delivery from Amazon as expected by now.

    These arrived in a surprisingly small but very heavy box (20kg) so be ready to haul this to the room of choosing.

    Once unpacked you’ll have:

    3 bars. One to make a barbell and the others for dumbbells.

    4 2.5kg weights
    4 1.25kg weights
    4 0.5kgs weights

    Very easy to put together as needed and everything feels study. These would be a great addition to any home gym for sure.


    – Great build quality
    – Good level of adjustability
    – Easily storable


    – Honestly can’t think of any, they do what they set out to do and do it well. Would definitely recommend for anyone looking for some flexible weights for home!


    Seriously Impressed!

    Before lockdown, sets like this were selling at less than half the price of this one, but now this appears to be a decent price to pay for a set which facilitates a wide variety of strength exercises, either as a pair of dumbells with up to 10 kg on each side, or a single barbell with up to 20 kg. The bars are 1″ diameter, and so if you have weights with same size, they will fit the bars too, as the threaded ends are generously sized and weights are easily fitted using the spinlocks provided. Everything fits in a carry case, for storage and transport, if required and it all feels like it will last.

    This cast Iron 20KG Dumbbell set arrives packaged very well and safely. It’s a heavy item and the box is well supported to avoid it opening during transit. Inside you’ll find the styrofoam packaging housing the weights in a very well packed order. All items were protected and free from damage.

    Included is:
    4 x 2.5KG weights
    4 x 1.25KG weights
    4 x 0.5 KG weights
    4 x screws
    1 x barbell adaptor
    2 x dumbell bars with padded grip

    The weights are cast iron and very high quality. No loose or sharp/exposed edges, fully smoothed and rounded to ease with picking up each one and a central hole cut out to slot onto the bar.
    The bar itself is strong and the 2 dumbbell bars can screw into the silver metal bar allowing you to make a long bar. This means packaging the product down is very easy as you just unscrew, using less space than required to store safely.

    The clips screw on to keep the weights in place. It can be a pain to screw on and off but this is the safest way to prevent injury or weights slipping.

    Dumbbells are comfortable t hold with the padded grip and you can make out each one for a total of 8.5KG + the weight of the dumbbell bar.

    Perfect for heavy rep exercises and multiple home workouts.

    At 80.00 this is a little pricey, compared to other sets on here, however, these are cast iron weights as opposed to the cheaper products available. A good quality set made to last.

    Compactly and safely packaged - a good set of dumbells/barbells.
