I bought mine new at a local sports store that sells new and used equipment. I don't remember the brand but it seems to work fine. However, I haven't tried it with hip thrusts.
I love my Valeo Barbell Pad! It was recommended by several here on this forum a few months ago. It makes squats and lunges so much more bearable...I don't like to get distracted with a heavy, uncomfortable, bar, lying across any part of my body. I tried the hip thrusts with it, and it felt nice and comfy cozy .
