I normally read review first before purchase a item but figure I be pretty safe with some light-weight dumbbell . I wish I would have read the review because now I have only 1 dumbbell in 3 different weight - thanks Amazon ! maybe just a note to buyer that the purchase be NOT for a set - which be normally how light weighted dumbbell be offer . now I be stick with purchase the mate which now make the item not such a good buy after all , it would cost too much for return shipping - ugghh !
