I order two of these dumbbell to do physical therapy exercise . my grip be weak and the neoprene make it easy to hold during any exercise . the number 5 on each end do not look as if it will last very long , but I have have that problem with vinyl dumbbell as well . the neoprene coating seem a bit thin , so it may begin to show wear sooner rather than later , but I definitely expect to get a few year of use from they . I do not really care about aesthetics when it come to these weight . they be both purple , as state , -lrb- darker than the current picture on the product page -rrb- and that be fine with I . the bottom line be that they be comfortable to use , have hexagonal end so they do not roll away , and overall be worth the cost . I will buy more of this brand .
