I had one with a nick directly above the front camera on the chamfer. It was kind of annoying. It had its own silver shine unlike the platinum one.
The home button was also too loose, there a was a gap on one side and I could move it to the other, lock button was hard to slide down and volume buttons were extra mushy. The weird calibration/screen panel relative to my first one (screen just stopped powering up after day 3) was what sealed the deal to exchange it. They only had black this time and I like it! Better for movies
This one has no issues that I can tell. Neither did my first minus a lock button that periodically felt stuck (whatever) until it went DOA on me.
