Mine couldn't go to black. Worst customer service I've ever seen! I ordered one of these directly from Fitbit in April, with expedited shipping. Since it was out of stock, I received it on May 4th. After hours of trying to get something other than gray on the screen, I then sat on chat for another few hours and determined it was a lemon. I shipped it back the next day at the Fed-X office using their label. I still don't have a replacement. The label they sent for me to ship it back to them takes 10 days to make it back. I was told they then have a few more days to look at it before sending out a new one (hopefully one that works this time). And, if I want a refund, that would take an additional 10 days. So, stuck now, no money, no Versa.
