“I purchased these because I was looking for strong resistance bands. Over time, my rubber ones snapped. I can say that so far, these are better than what I expected. The black band is my favorite. The only reason why I hadn’t given it five stars is that the description says that these bands are all the same size in circumference. After use, the grey one has definitely stretched out a bit. They also do slide up your leg while working out. But the resistance they provide outweighs these little quirks.”
