The finish seems fine for the piece I received. Didn't get any splinters or rough edges. Treated it with mineral oil overnight, it now touches and smells great. Just slightly too short for 68 layout but really can't complain for the price. Wish they offer more width options for TKL and full size as well.

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.
