Overall, these pads are comfi and durable. Pretty light and can be fixed reliably on a knee. they do not slide down being wearied over working pants. Of course, elastic belts need to be appropriately adjusted. They are very soft, and knees do not hurt even if one stays kneeled for a few hours.I found two small issues though.First one is plastic is a bit slippery on metal and plastic surfaces. A couple narrow rubber stripes would be really beneficial.Second issue is height. When one need to step left or right, it is easy to put knee at an angle causing the pad to move aside of one's leg.
