Warped Wood
Color: Black Walnut
I know it's inexpensive, but regardless of the price of an item, it should do what it's meant to do somewhat effectively. The wood was warped and did not sit flat on my desk.

Great wrist rest, advertised dimensions slightly inaccurate.
Color: Black Walnut
Perhaps this is nitpicky but I purchased this wrist rest because it was perfectly sized to my keyboard at 29cm wide. It got here, and it's a fine wrist rest in terms of quality, material and feel, but it's not 29cm wide, it's 30.5cm wide. The other dimensions are accurate enough - both only .1mm off, but the mismatched width against my keyboard is enough for me to notice it and obsess over it. If that doesn't bother you, I say go for it. At $15 it's a good deal.

Fairly priced but the finish leaves something to be desired
Color: Black Walnut
This wrist rest looks very nice, but I'd give the finish of the wood a C. There are a few rather rough patches, one that feels like it will develop into splinters eventually if it's not refinished. I'm using it for now, but I'm definitely going to refinish it at some point and it's inspired me to make my own wrist rests from scratch out of hardwood. I gave this two stars because it's very pretty and it's fairly comfortable to use. The wood used is pretty expensive, so I'd say that the price of this item is rather fair. I just wish they put a better finish on materials that are so nice.
