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 :)

Good starter set
Brought for my son , the weights are solid and appear well made , good for starting out and enables him to cover lots of different exercises , the only reason this is a four star and not a five star is the extension to make a barbell , just doesn't seem long enough or feel right , as dumbbells these are solid and quality at a decent price range .

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. :)

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.

Good purchase
I’ll start by saying it was not my first choice. My choices were limited due to everyone thinking the same an ordering well before I did.It’s a neat set, when dismantled doesn’t take up much space, keep the box for the other plates not in use.It’s every thing I need but wish the attachable bar could be utilise on its own. This would support a quick change from bent over row to dead lifts as you’d want more weight for a dead lift.The utilisation of the bar would support a quick change over when doing a class.I use lifting gloves so have no issue with the feel of the bar.You have plenty of plates in combination to chose from. The securing nut is easy to operate but as I’ve said if you need a quick change over it’s not ideal.Good value for moneyAnd I would recommend to a friendNo issues with deliveryI’m made up with it as I’ve never had weights or any fitness equipment at home before.

Great weight set
I was a little nervous about ordering these after reading some reviews, so when they arrived I was pleasantly surprised at the quality, they look good and genuinely feel really good, assembly is really easy so swapping between different weights is a doddle, my only concern is the extension bar, it does feel a little loose when you have all the weights on it, having said that, the threads do go in quite a way so I doubt they coul fall off, I’m really pleased with my purchase
