I have carpal tunnel, this wrist rest works but not very comfortable. I only bought it because it's a Razer product and I was trying to add it to my collection. I bought it for $9.99 but I'm pretty sure Razer makes them for $2 max. Not a very good product, ok at best. It's slightly curved, making it unstable on flat surfaces, and there's almost no cushioning material, so it's still putting quite a bit of pressure on your tendons. To be honest, I'm sure you could find a $10 wrist rest that's a lot more comfortable - I wouldn't pay more than $5 for this thing. Disappointed with Razer even for making such a cheap and useless product, but they do this with some of their mice - so it's not a complete surprise.
