Low profile keys are a problem. Since it's 4 keys there's possibly a fracture of a trace on the circuit. The keys themselves are typically damaged by removal efforts. The laptop I am currently using has its 3rd keyboard installed, which I expect to last for a long time because I got a full-travel keyboard that attaches to the USB port. Keyboard #1 kept failing from microscopic parts of the key mechanism breaking. Keyboard #2 died in a similar fashion, hence the full-travel keyboard, but then moved to generating keystrokes without being pressed. Keyboard #3 isn't going to have any particular use except making the computer happy that there is one when it boots up.
It's a shame about the Belkin, that looks expensive. The full travel USB keyboard was $20, I think. It's also got the full numeric keypad as part of it, which laptop/iPad keyboards don't have.
