I have a Kemper and I love how Kemper owners here want this thing to fail solely based on some message board conversations and YouTube demos.
Competition is a good thing, and if the Kemper truly is superior, time will tell and it will win out.
This is why we can't have nice things because everyone has pick their product to own and defend their purchase. How about just enjoy what you have. Actually, I have an FM3 here to play with too and still have a QC preordered so for me whichever is best for my situation I'll keep, the rest get sold. It's pretty simple.
I've wanted the QC to succeed and would've even demo'd one if it weren't for their stupid cloud requirement.
