Teenage Engineering CA-X Plastic keyboard cover

I was afraid that I would "lose the feel" for the buttons, but I generally find it more comfortable to hold the PO with the mask on. The only problem at first is getting used to the fact that the buttons have icons instead of names - but the icons make sense. The only drawback is that the rubber is so sticky that it attracts small hairs and dust - and it's hard to remove because it's not completely smooth. Someone might find it a disadvantage that they have to tear the "hanger" off the PO to be able to put on the mask (or have to cut a hole in the mask).
