I recently start a work out routine which require I to work with a different level of weight through different segment of the work out . I want to save room -lrb- and money -rrb- so I purchase this set . I be so excited about it because it appear to be exactly what I need . however , my excitement turn to disappointment as soon as I put these weight to work . First of all , it be not as easy to change out as I hope it would be . I be behind in my class because I have to fiddle with the grasp while make the adjustment . it be not slide in and out as easily as it should have . second , the grasp actually start to pull itself out as I be do bicep curl ... bicep curl for cry out loud ! Third , the product be shaky and flimsy . as I be lift and work , the weight do not feel secure and would click and clack against each other . when the time come to do some overhead triceps extension , I put the weight down and use another weight instead . I do not feel safe put this thing over my head . heck , I do not really feel safe have it anywhere near my body . I purchase this item because it be affordable compare to other adjustable weight I have see on the market and because it have get such good feedback here . I scrimp and save to buy these bad boy and they turn out to be bad toy . I return the product and stick with regular dumb bell . maybe I just get a bad , defect set , but either way , it be a bad and disappointing experience .
