I've got a noppoo and it seems that way, maybe those keys are just broken, maybe no soldered down properly, broke along the way or whatever?
I'd RMA it, send it back and get a replacement, probably the best thing you can do right now to be honest. This sort of thing happened to me when I bought my second Noppoo, I got it from amazon, it arrived, it didn't work (I believe the K key didn't work and what not) so I sent it back and got a replacement.
