Nuobell 580 Adjustable Dumbbells, 5-80 lb, Set of 2 Free Weights

I have been using the adjustable 50 pound core fitness dumbbells for about 8 years now and never had issue with them, other than they are limited in weight to only 50 pounds. I got the 80 pound adjustable nuobells as an upgrade, and boy are they awesome. When I first opened the box one of the dumbbell cradles had a cracked plastic part that made it more difficult to rerack the weight. However, after emailing customer support, they sent out a replacement cradle to me that same day and at no charge, and it arrived after about a week. I won't dock a star for the item being slightly damaged out of the box because sometimes it happens. Now onto the dumbbells... Pros- The cast iron plates just look and feel awesome. No issues with the plates feeling insecure and the plates themselves are very durable. I love the handles! The steel grip with the knurling feels like an actual gym dumbbell. The 80 pound max weight is such a game changer for me. While 80 isn't quite enough for some exercises (chest press, db rows, shrugs), it is still enough to get in the work I need. Huge space saver and much more economical than getting 16 different pairs of dumbbells. Cons- Some connector parts of the dumbbell are plastic and only time will tell how they hold up. You can't just drop these. Although it seems fairly durable, you will most certainly break the plastic connectors if you are carelessly throwing them around. Not that I would drop them anyways, but you just have to treat them with respect. If you want dumbbells you can abuse and drop, then you need solid cast iron or rubber coated ones. This product is an absolute must have for any home gym. The price point is very high, but this is absolutely worth it. Edit: I have been using these for over a year now and they have held up flawlessly. I frequently use the full 80 pound weight and the plastic connector pieces are showing no signs of wear. Just treat them with respect and as long as you arent dropping them or aggressively reracking them, they will hold up fine. These are the best investment I have ever made in my home gym, they are worth the price!

These are very well made and they look great. The handle has just the right diameter, length, and knurling to them. The overall feel of the dumbbells is quite balanced- like you’d find in a high end commercial gym. Selecting the weight is a breeze and taking them in and out of the cradle is effortless. But here’s the thing- you can’t treat them like trash, toss them around, force the selector, and expect them to function. I see people complaining about them getting jammed or “breaking” without dropping them but when you zoom in on their pictures you can see they have some of the weight plates upside down. There’s a clear top and bottom orientation to the plates and you need to read the instructions or at least follow the pictures when setting up. Some people put these together the wrong way and wonder why they can’t get them to function smoothly. User error. And of course you can’t throw them on the floor because they weren’t designed to take that type of punishment. They are designed to be used, but not abused. If you set them up properly (5 mins), and treat them respectfully, you’ll be rewarded. I think they’re easily the best adjustable dumbbells I’ve owned. Worth every penny

Is very nice set, very compact with lighter weights..! This the best set I ever had..! What I like the most is that the weights stays solid, not clapping around.

I like these better than the bowflex adjustables. They feel more like the real dumbbells than anything I’ve tried before.

This is truly an awesome product. I purchased the original concept of this in 2001. The Powerblock. I have seen this type of product evolve through your the years and the Nuobell has developed the closest so far to the real feel and function of a dumbbell. Easy to use, sturdy and very well made. I would suggest applying WD-40 once every 6-8 weeks to keep the mechanics smooth and rust free. My set is kept in a humid environment and this preventative steps helps significantly. A product I would definitely recommend.

DO NOT BUY, CHEAP INTERNAL PLASTIC COMPONENTS THEY WILL BREAK. DO. NOT. BUY. Seriously they cannot even handle the weight load they can go to, their track mechanism is literally a plastic wheel from a playtoy

Great packaging and product!

These things are great, BUT.... warranty support ... kind of a mess. I'm not a "weight dropper" type / idiot. But eventually it seems these handles will break and fail to dial up the desired weight. Then what to do, but reach out to the manufacturer for warranty, right? That's what I thought. If you buy through a reseller (in this case finer form) NUO will refuse to support it and push you back to the reseller. The long story is many of their support folks basically called me stupid for reaching out to them... the word was "common sense" to not contact NUO ... for a NUO product... a really odd policy. To me there's return support 30 days ... what not, and then manufacturer's warranty ... from the ... manufacturer... cuz it's in the name ... "manufacturer's" warranty .... If the amazon orders link to the vendor (finer form) was open, that would be okay I guess. It was not and I'm less than 1 year. So eventually I got was able to find Finer Form on their website and get them to respond and they are going to make it right. But what a mess. Harder than it should have been.
