Soft and cute
Color: White Ice Set, Color: White Ice Set
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.

Helping my daily work life!
Color: Black
This has minimized my arm, wrist and hand pain. It’s soft, sturdy and stays in place. Reasonable price and would recommend if you want something with solid quality.
