Overall solid entry-level adjustable dumbbells. Nice that you can pick up a pair for less than $400. The handles adjust nicely and it is satisfying to hear the "click" for each weight increment. They only go up to 50 lbs and there is no way to add additional weight, so that can be limited for some of the larger compound exercises. The individual weight plates are coated in plastic and sometimes stick in the rack which is annoying. I wouldn't trust dropping these. I will eventually upgrade, maybe to Ironmaster adjustable dumbbells to access heavier weights and keep these to easily/quickly switch between lighter weights.

I've had these for a little over a year and they've actually been pretty great. They are pretty much all plastic but I haven't had any issues with anything breaking. The handle twisting weight selection is smooth and fast. I don't have the stand, so the weights sometimes stick in the cradle at the higher end of the weight selection when you try to pick them up. I just stick my foot on the cradle to keep it down. They're not the most compact and there are definitely better adjustable dumbbells out there but I'm not sure if you can beat these for the price, at least at the time I was shopping them.
