I like these inserts a lot. I've had them for a couple of years, and have had no issues with the quality. I may have bought too large of a size for my women's Carhartt jeans, but it just makes it slightly more challenging to insert and remove them. Often, I just leave them in my jeans and wash them in there. I'm an electrician so am not too hard on my pants, but it's great padding for my knees on OSB floors and in the dirt and in crawlspaces.

One of the pads' foam cracked within a couple days of use. Still held together by the spandex backing, but I don't trust it to hold up for long before I've got multiple pieces of foam floating around in the pad pocket.
