So far I'm pleased. The product is made mostly of steel and looks like it will hold up (unlike the all-plastic types). I've repositioned it several times looking for just the right spot where it will support the arm I use to move the mouse, and it seems to be reducing the soreness I can feel after a long session at the computer. It looks very much like products that cost a lot more so it appears to be a good value. Only if this product doesn't stand up over time will I be disappointed, but so far I'm happy with it. If if holds up over time I'd give it another star.
