NÜOBELL S 5100 Black

I've been using these for a month or so and am very happy with them. Changing weights is fast and buttery smooth. They are exceptionally solid feeling, well-balanced, and I prefer the lighter knurling than you would find on some competing products, like the REP adjustables. They look great, feel really great in the hand, and have an overall sense of quality design and craftsmanship.

I did have a quality issue - one dumbbell adjustment began to fail after about a week of use, but Nuobell service is excellent, responded very quickly, and replaced the impacted components with minimal fuss.

I have some nitpicks:
The inner surface of the weight stack (ie, what your hand would touch on either side if you're gripping the handle) is both plastic and irregularly shaped. This doesn't impact traditional function in any way, but if you wanted to hang these from a chain for weighted dips/pullups, I think they'd be damaged. It also impacts movements where you would grip the dumbbell by the inner surface - such as dumbbell pullovers, two-handed tricep extension, etc. You can do it, but the fact that it isn't a flat surface can make it uncomfortable and makes me worry about dropping one. By contrast to REP, these do not have the extra support bars as part of the handle, which I much prefer. But those support bars can be used to hold onto for pullovers and extensions - with these, I feel like you're left kind of without good options.

I don't drop these and can't imagine why I would. Even with fixed dumbbells, I've never found the need to throw them to the floor after a lift. Maybe that's because my home gym floors are uncovered and I'd wreck the floor as much as the dumbbell. But the innermost weight plate is really thin and potentially fragile. If you're doing lateral raises, for example, you must ensure you don't clang them together at the bottom of the eccentric, as it does seem like it would be easily possible to bend the inner weight plate, which would mean the heavier plates won't align correctly. All of the weight plates other than the inner one are very robust and well-designed. I do wish Nuobell could come up with a way to make the inner ones stronger as well as make the inside surface of the handle non plastic.

So far so good, has worked very well with the quick change to adjust for different exercises. And durability construction is good.i like them so far and but only had them about a month. I would recommend them to a friend.

convenient and easy to use. I love the grip on the handle

Beautiful aesthetic and well thought out design. Assembly only took a couple minutes total for both sets to be completed.

I used them for the first time today and I was really happy with the balance and ease of use. I will say that it is taking somewhat of a new level of trust having them over my face for bench press exercises. I’m not sure how the plates stay together at all angles but they do exactly what they are intended to do and it’s really cool.

If you’re short on space or on a budget and want a full set of dumbbells. This has to be the way to go.
$1,000 for 5-100lbs dumbbells is a steal. Way better than $4k+ for a full set of traditional dumbbells.

I bought the dumbbell stand and wasn’t able to use it since the 5100 is a larger product than the 580s. Luckily NUO already has a solution and my adapter is on the way. Looking forward to even more ease of use once that arrives.

Happy customer here!

Solid dumbbells, everyone is busy overhyping the peppins. I don't know when everyone's grip strength turned to shit but these are way better and all you have to do is not drop them. Quick and easy way to change weights and no cage? Perfect. I wish the cradle was all metal with PEX to protect the weights, if I'm spending $1000 I wish they stepped the quality of that up. Overall, however the best dumbbells on the market for anyone who doesnt need to slam their dumbbells on the ground because theyre ego lifting in their home gym for their cat.
