I bought this wrist rest in like new condition for $6 and I will say it’s 100% worth MSRP at $15-20. The weight is nice, it doesn’t slip on my mousepad. It’s very comfortable to rest my palms and wrist on. The sizing pairs well with my 80% keyboard. It functions as it should. I use this at a stand up desk on an industrial shop floor to help put my wrist at a better angle and it works perfect.

Decent; does the job

Size: 100% Standard

Cushion feels very porous and thin. I suppose you can call it memory foam because it basically sunk where I usually rest my wrist and has not returned to its original shape (lol). The small rubber pads on the underside help a bit but slip resistance would probably be better if they covered a larger area. Overall, it's not bad for sub $20 full size kb wrist rest.

Is does the job, love it.

Size: 60% Compact

Is really comfy, it does the job, you can't go wrong with it. Just buy it if you have a 75% keyboard or less because is not long. For me is not a problem.

Nice wrist rest

Size: 100% Standard

Comfortable angle, solid enough to not move around but soft enough to be good for long term usage.
