These adjustable dumbbells work really well. Lots of weights to customize them to. Very happy one year later! They save so much space from normal dumbbell set.

I like it! It’s been a while since I used free weights but wanted to start again since working from home was making me soft. When I did have free weights at home a while back, I rarely used two dumbbells at once except for maybe lunges. But having two now is much more convenient. I still do individual arm workouts and have one at more weight for bicep workout and one at lesser weight for triceps. And for leg day, I’ll pack on the weight on both sides. So far switching weight has been smooth. The grip is good. It’s plastic with smooth rubbery texture. The weight feel well made and don’t jingle around like typical free weights. I did also order BowFlex dumbbells before this and returned them cause they felt wider. I’d say the quality between the two brands are about the same with this brand being slighter short, which is a good thing. As for caring for them, I just give them a wipe with light soapy water and dry. I don’t drop them after a workout either. I wouldn’t trust dropping any dumbbell that has small moving parts tbh. I also like that they don’t take up much space and can be hidden away if I have guest over. All in all I really like them for the price point.

Gift for a close friend. They absolutely love it and indicate it has completely changed their approach and attitude toward workouts as adjusting free weights is no longer a chore. I own the name-brand version of this design and they have worked well for us for over 10 years. These are not dumbbells you can knock around and drop on lifts, you need to be careful and deliberate with them. With proper & controlled use, I see no reason why these wouldn't last a very long time. In an ever-expanding sea of product gimmickry, these adjustable dumbbells (and similar designs) are one of the few items of home gym and workout equipment inventions that I think are truly revolutionary and indispensable.

Packaging arrived in tough shape but the product seemed to be just fine. Seems very similar in quality to the Bowflex set I have. Adjustment knob is a bit stiff to rotate but im sure it will loosen with time. It seems like great value for the money.

Great Dumbbell Set I so glad that I chose this one instead of the one for 5-55lbs that turn with the handle increment of 5lbs-50lbs: Feierdun, Instead the knob turn on both sides of each weight and the packaging was excellent and shipping faster the expected delivery. But if your thinking they're to big, not for me I believe that's only if your a p woman of a small man because I'm 5'11" & 160lbs to me they're the right size consideing it's a 15 in 1 dumbbell to me it's Worth Every Penny! Get your now! 4Real!
