I must say in advance that I've never had a keyboard that was as pleasant to use as this. Ergonomics is for me really unbeatable, the keystroke almost perfect. But while dusting the keyboard broke two buttons. I thought that would be easy to fix and tried to lock the buttons. That did not go. The law approved plastic of the plastic spring was already broken and thus I have to throw away an expensive and really great keyboard because two keys are no longer installed. The keyboards can that cost maybe 1/5 of the price also.
