Fitbit will not light enough to see and only when on the charger. You cant even tell what it says. When putting it on your wrist it shows nothing. Ive never wore it at all. I put it on the charger as soon as I got it Saturday July 10th and after being on the charger for 4 hours I took it off and checked it and you see nothing. Put on the charger again and it so faintly lit you can hardly read it even in a dark room. My last two were very bright.
