[This review was collected as part of a promotion.] I don't use knee pads everyday like some people do. I might use them once or twice a week at most. With that being said this is my review of this product. 1. They protect my knees when kneeling on gravel and concrete. Anybody that has ever kneeled on a rock knows what i'm talking about. 2. The straps do not cut into the backs of your legs like some knee pads do. 3. They are made well and hold up to every thing I have thrown at them thus far.Once again ergodyne has made a product that I can actually use for my needs. Thank you for saving my knees...
