This is an accurate and durable weight. I have read numerous articles about free weights being off. I weighed mine and they were accurate. The only thing that kept them from getting five stars is that they are on the bulky side likely due to the neoprene coating. I am female 5'7" with long thin fingers. If my fingers were not on the longer side it may be hard to grip these well. They work for me, but I would be careful if you have tiny hands.
