In case someone is smart enough to read these posts before buying a Sana clip. Got a brand new one for Christmas and the display is blank. Get the blue light around the control but blank screen. Tried the reset several times and what tech services said to do, which was obviously read from the same manual I had, and nothing worked. After waisting several hours hoping I could get it to work, now get to waste more time returning it. Seems like a little QC would at least ensure the thing works before shipping??? Any ideas or similar problems before I return it?
