my Minibrute arrived today, it sounds great but has a few issues.

the first thing i noticed, is there is something rattling around inside. on closer inspection, 2 key weights are missing from underneath the keys. one of them was found inside the packaging; is it possible for the other weight to have fallen inside the mb causing it to rattle?
the other problem is my MB doesn't lay flat on my desk.
i'm not sure whether to send the machine back, or try and mend these issues myself. i will contact support and see what they say. if anyone has any advice, i would be most interested to hear your thoughts, cheers!
