I order four of these . for starter , the handle on the weight have metal shard so watch out or you 'll get cut . as soon as I realize this I take they out to the shop and wrap the handle heavily with duct tape . this will work ok but I certainly do not expect that from what be suppose to be a finish fitness product . also , one of the dumbbell have a loose end . one of the hex head slip up and down about a quarter inch . since it be not worth the trouble to pack these back up and ship they , I 'll just count this one as a live and learn . should have just go down to my local store for this one .
