I used these a TON recently as I have been doing a lot of home improvement projects. Kneeling inside on tile, outside on grass, or on my concrete driveway, it was taking a toll on my knees. I bought these and HOLY MOLY the difference. No more pain in my knees. And I can honestly feel the difference even on carpet as funny as that sounds. I can't explain how life changing these have been. I'm no professional, but I recommend these to any DIYer. You will inevitably KNEED a good pair of knee pads.
