Query: Pads someone's pocket

Fluid Forms 1002F Patella T knee pads are one of the most disappointing purchases I have made. The pads slide from side to side and slip top to bottom. Because I am on a fixed income I try to purchase the "best" but I sure was fooled this time. In addition to crawling around alot, I also fall often due to MS and I count on knee pads to take some of the impact. My previous pair of twenty dollar pads peformed vastly better. Someone send postage and you can have them. Me, I'm headed for town to buy another twenty dollar pair.
