The Nexus 6 is ok, I must've gotten an early one because the back of mine started separating and & had to get a new one from Motorola about a month ago. I only had it 2 months. I'd trade it in for the new Nexus 5, I'd have to see what it looks like tho
How long did it take Motorola to repair/send you a new Nexus? I sent mine in just this past week because the back cover was "peeling off" and although the guy on the phone said 5-7 business days.. I don't even know
