This is a good protector for the keyboard, but the design has no leeway in movement, making it difficult to get the keyboard in and out easily.
It also seems to be leaving fluff on mine, which is not a great thing for electronics to have dust etc getting in, especially off it's own case!
It does protect if from scratches etc and does what it says on the tin though so I would recommend it if you own one of the CME Xkey 25 boards and want to protect it in your bag as you carry it around.
