Went to Verizon to check out the new Z30. After the no mind employee directed me to the Z10 display and then to the Motor x display. She finally figured out where the Z30 was. Verizon hires some Really Dumb and poorly trained staff. (Brea CA store). Anyways after holding it tethered to the wall I noticed the thin metal tab that covers it card slots was already bent. This was part of the back cover on the display unit. How is it holding up in normal use?
