I love this perfectly-sized and shaped board! I wanted something to tilt my daily planner up so it was easier to see and write on throughout the day. Book stands just don't work for my use. This tucks under my computer, so it frees space to work (see photo). The wood, the soft edges, and its finish are well crafted and beautiful. The pads on the bottom keep it from sliding on my desk. I'm thinking about buying another for my home in a spot where I read every morning.

It's a chunk of wood! Perfect.

Color: Black Walnut

It's a chunk of wood! Finish is great, height is great, looks great. Easy to clean unlike foam ones. I did get one that was warped but the replacement was fine. Just check that it's actually flat when you get it

Decent product. Fits perfectly for 61/64 keys. Just slightly short for 68.

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.
