According to another website selling this product, the 88 key cover measures 16" x 48". Should fit more "standard" 88 key boards, but not extra-long or extra-slim boards (like my Privia 575 which is 53" long). Just FYI for those with different sized boards.

Same material and same features as some of the more expensive name brands. Put the savings into adding something else to your gear. The Keyboard Cover works just fine for what it is. I would give it a higher rating if somehow they could make it as lightweight and stretchy as it is but waterproof too. It keeps the dust off okay, but I'd also like to protect the board if the sprinkler system in our practice site were to ever go off.

I wanted to use this in between sets on my Roland RD-700SX, but the thing doesn't really fit the large-scale keyboard. Even when stretched to its fullest extents, it wouldn't stretch around the keyboard enough to stay on when I let go of it. I guess it would work for smaller keyboards... ?
