I got these a few days ago and already used them. Last week I had to get on my knees to get something under the bed and my knees hurts for 2 days. Now I am a large person so I have a hard time but I usually don't have a problem putting my knees on the floor or ground to do or pick up something. Anyways, I put these pads on and finished my project and had no pain while on the floor. The straps are wide and velcro which is good, but was a bit uncomfortable for me but I am sure as I use these, the straps will soften up some and be better. Right now they are rigid and cut in alittle, especially if you are wearing shorts as I was and the straps were directly on my skin.
I recommend these pads, gowever, I don't know how the would hold up with everyday use in a work setting as that is not how I used them, but they seem that would last.
Thank you and have a nice day.
