great mouse rest
Color: Golden Oak, Size: Mouse Wrist Rest
This works really well for for elevating your wrist, I use an apple trackpad it puts my wrist a little too high so what I did was put some rubber pads on the back of my trackpad to raise it up. It now gives the perfect height and good support I can even lean on it. It works well to the fact that it gives you very good support it's not uncomfortable and it's very easy to clean and looks very nice on my desk, because it's made out of real wood.

Great wrist rest. Smooth finish, good looks, and ideal wrist angle.
This wrist rest sets you up for pretty optimal, level height to prevent future wrist problems. I went with the nice reddish/brown color as it matches my brown wood Edifier speakers and other brown accessories very nicely. Nice matte finish that avoids showing finger prints and skin oils. The color is perfect, not too red or too brown.
Keep in mind if your keyboard is angled in the front it will leave a bit of a gap, however it is unnoticeable to me. Also, make sure your arm rests of your chair can come high enough to meet the half inch or so thick wrist rest. My arm rests are a bit low for the time being so some extra pressure is put on my arm behind the wrist when resting on the chair supports.

Not for me
Color: Golden Oak, Size: Mouse Wrist Rest
It's tough to review something like this that functions perfectly, but just wasn't the right fit. The Glorious wrist rest for the keyboard is perfect and exactly what I wanted/needed, but the mouse rest caused hand and wrist pain. I swapped it out for a squishy alternative and that worked much better. I have a theory it might have been due to the relatively low height of my ektecity gaming mouse relative to the mouse rest. My keyboard is a higher height and that may be why the wood keyboard rest works so much better.

Neat and Square
Color: Black, Size: Square
This turned out to be durable and looks good on my valet table. The difference in the way it snaps to the sides, keeps the corners square and looks better than the other models that force the corners to extend outward.
