Recently, a little son spilled sweet compote on her. The keys started to stick. Dismantled and decided to wash. From previous keyboards, I remember that clicking buttons and putting them back in is still a hobby. Here, the buttons are grouped in a rigid backing. I just snapped them all out and washed them in soapy water with a brush. They put it back with my son and taught the letters. Everything fell back calmly. Everything works as it should. Not all third-party keyboards can do this. Altogether five. Feels like a breed.
