Gear Geek has posted a review of some HSS kneepads that he’s tried out and posted some positive comments:
I have been using these kneepads for several months and they’re still in excellent condition.
Durability seems to be great and comfort is good as well. One thing I notice about these kneepads is that they do stay in place so they’re where you need them when you need them. (Gear Geek)
