Query: Could have been good..

Well I bought this based on: it had a good layout, nice feel, and cool backlight.A few months later I discover that there is a fundamental flaw, however:Eventually, if you do not strike the keys precisely on-center, they have a tendency to "get stuck" on the mechanism underneath. This is quite frustrating, to be typing along, and suddenly come to a halt because you just bashed your finger on a key that isn't moving down.So, unfortunately, I am on the search for another keyboard already.
