Okay
These are as advertised. I got the 30kg set. The bar weight is included in the overall weight. So the plates add up to 27kg. The plates are well manufactured. They are a bit smooth and slipp about easily. The other ones I already own are a matt finish that is not shiny or slippy. I find them better than these weights for that reason. The shape and size are different to the plates I already own which I did not expect. I thought all cast iron 1" plates Wouldham some kind of universal diameter and thickness. It seems not. These are larger in diameter and thinner. Obviously this changes nothing in terms of weight. I can still use the old weights and These new ones together, however I will probably match each dumbbell and each side of the dumbbell for symmetry and in case of weight distribution differences. The box came quite damaged and completely open on one end. No parts were missing though so I am still happy with purchase. I went on to find a 20kg set that was cheaper to the point that I coukd have bought 2 of thse sets to get 40kg with 4 bars for the same rice as I got this 30kg set that has only 2 bars and a mid joint I will probably never use. I didn't want the hassle of sending this set back when there is nothing wrong with it for the better price to weights ratio. I would recommend this set but would also recommend researching other sets and working out how to get the best quantity and quality for your bucks.

Great set of weights for any serious beginner.
Needed to do something about the belly and 'love-handles' that appeared over the past 2 years of lockdown! Was thinking of joining a local gym but... you know how that goes. So, decided to invest in these and build up towards my home gym. They were delivered in sturdy cardboard box which can be used to store them when not in use. But, for me, these will always be out on the floor. Otherwise, out of site, out of mind! I've had concrete-filled, plastic ones before but this time wanted cast iron ones which hopefully won't go rusty over time. The bars are chrome plated whilst the weights are finished in a hammered effect, dark-grey paint. Looks professionally finished and of high quality. Other reviewers commented that the screw-locks loosen during use, but I haven't had that problem. Really like the extension tube which converts the two dumbbells into one barbell. Not sure if I would trust loading the full 20kg with the extension bar, though. As well as bent-over-rows, bench presses and fore-arm curls it's possible to place the bar-bell on the floor, slip your toes under it and knock out a few sit-ups. The different weights are ideal for a beginner. Even the hand-bars alone, without any discs, are a good way to start, adding weights as you progress. I've used these daily for the past week and was ready to buy another set. There's always a 'however'. However, the price went up by £10 right after I got my first set. So, just waiting for the price to drop, or until I find another seller with a similar product and better offer. I will be buying another set, a folding bench, and a Straight / EZ Curl bar-bell, all available from the same manufacturer.

PROIRON 20kg Cast Iron Adjustable Dumbbell Set
For the past 3-months, I've been "trying" to lose weight & get in shape, in fairness it's been going great. Now that I'd lost a fair bit, I felt now I needed to up my game (so to speak), and wanted something which wasn't going to cost me the earth (as it's still early days), did the usual research (thanks You-Tube lol), and set out my budget, and what I would need (to start off), saw a few items but this product seemed to stick out for me. It seemed to have decent reviews (setting aside complaints for broken or damaged items - it happens), plus thanks to the people here who took the time to provide photos too, I decided to take the plunge. All I can say is, I'm really glad I did. Really solid build, and the quality is good too, one of the things that "sold" it to me, was the middle "extended bar", which is a really good idea, but after about a week, I got tired of attaching/ removing this item, so decided to purchase some extra Pro-Iron (Cast Iron) Weight Plates, and a York Fitness Spinlock E-Z Curl Bar (5 kg) with Collars. So now I have a set of Dumbbells, and a Curl-bar. As said previously, all items are of great quality, and I've obviously bought more weights by the same reseller. Packaging for this item was really good, very compact and well protected, the box it came in is deceptively heavy (due to the small size) so much so the delivery guy asked how such a small item could be this heavy lol. Anyway, I'm starting to ramble now, all I can say is if you're in a similar situation as I was, and can't decide which Dumbell set to buy, you can't really go wrong with this, as I said I've had no problem with this, plus I bought some more weights, if I get to the stage where I move (to a larger place) then it might be that I consider looking at getting a multi-gym, but for now I'm stuck for space, and these do the job. :)

Handlebar weight
Incredible weights. I've had them since July 2025. Just so you're all aware, the bar and spin lock weight is 1.6kg (without weights). Just something to bear in mind :)

Proper gym-quality weights for home
If you have used weights in a gym, you will find these weights perfectly familiar. The advantage is that you can vary the amount of weight on each short bar and even use the connecting tube in either of two ways to make them into one barbell. After a few weeks of lockdown, I intend to start with them at about 6kg each and slowly build up through the summer. Only really strong people who want much heavier weights will find them insufficient. They arrive in a small very solid box which is difficult to carry, both for the courier and then yourself, so you need to exercise caution. If you want to do exercises that require you to swing the weights repeatedly in a lengthwise direction or to twist them while swinging them, then you would probably be better off with fixed dumbbells rather than variable ones like these because with these the ring weights are held in place with a large nut that would work loose with those movements. These are suitable for traditional weight-lifting movements, but you can still find plenty of variety of those movements available. For me they are ideal, but lighter fixed weights would allow those HIIT kinds of exercises more easily. With gyms closed down, and then the issue of whether air-conditioning is safe when they open up, I think these are life-savers. My previous set lasted decades, but I kept them in the garage and they eventually rusted away. I expect these to outlive me by a long time. Also, they were delivered very promptly, ahead of the expected delivery date, by a very strong man who warned me from his van about how heavy the box was - very sensible. I am very glad to have them.
