I be hesitant to drop almost $ 200 on this set of weight without see it in a store and know it be non-returnable . however , I have only use it a few time and I have be very pleased . I be motivate to work out more . they be very compact to store and very comfortable to use . I think this product be very well design . I wish I would have find this 10 year ago . it would have save I from lug all these hand weight from apartment to apartment when I move around a lot when I be younger ! such a great alternative to keep a whole set of different weight .
