I really like this case. My day-to-day purse is large and unwieldy, so it's really convenient that I can just stick my driver's license and debit card in the phone case if I don't feel like carrying it. However, the case covers the buttons, and the built in button covers are very stiff. The volume buttons aren't so bad, but pushing the power button definitely takes considerably more force than when the phone was naked.
I've only dropped the phone once (on carpet) and I noticed that the case popped open when it hit the floor. The phone wasn't damaged, but if you're looking for a case to protect your phone, this may not be what you're looking for. Build-wise, the case seems fine--the magnetic latch is still holding and doesn't seem to be separating from the case at all. I have a tendency to play with the latch, so if I had received a bad one, I would have noticed.
