I love the size, I have a 75% keyboard so I knew size wouldn’t be an issue. I love the color it matches my keyboard perfectly! It feels nice to rest my wrists on but I haven’t used it consistently just yet so I’ll update this if anything changes but it feels soft and nice. It’s thick and doesn’t sink in when pressure is applied. All round it’s great thus far!

Good wrist rest

Color: Black

Comfortable wrist rest. The gel is a relief, replacing one that was not as padded. This works great. I put a little strip of Velcro tape to affix it to my keyboard, works great.
