Is it always the same key or a different key?

I have a brand-new 50g that has a troublesome key on it. First I thought I wasn't hitting it squarely but running the keyboard test and in use the key takes very deliberate effort to register although all the other keys are fine. This is really annoying and a little disappointing.

I guess the 30b and 50g keyboards don't have much in common but maybe I am wrong. They have at least this symptom in common.
