Best Fitbit Zip Wireless Activity Tracker Lime Green

Product Name: Best Fitbit Zip Wireless Activity Tracker Lime Green
FitBit Zip Wireless Fitness Tracker! Lime Green tracker with green silicone clip case. So tiny, lightweight and convenient!Great preowned condition, works great, but it hasn't been used in a while and I cannot find the manual or the “key” toggle to open the back and put in a new battery. You will need a key toggle or know another way to open it up. There is a little scratching on the back where my husband thought he could open it a different way (men...lol). The Zip syncs up to your phone wirelessly and you can pair up to the Fitbit app to see your daily, weekly, and monthly progress! I best ship fast! Thanks for looking!.
