Bests & Worsts Reviews from Amazon

I finally received my Fitbit and unfortunately it just has a black screen. I followed all directions, which is charging it and pairing it up to my phone. But as it was paring, the screen just turned black and when my phone tries to finish the set up and asks me for a 4 number pin, I can't type them in because I can't see them. I tried a reset by placing the fitbit on a charger, and nothing happened. There is a vibration when I press the button, but nothing more. I really needed this to work by tomorrow and now this happens. It's a great disappointment.
