## Questions & Answers

**Q: Since most of the complaints are about the wristband. Is there anything out that you can use with the wristband to keep you from losing it?**
A: i came across this fastener. I've never used it myself since my wristband is holding up fine. I rarely take it off tho. http://www.amazon.com/MDW-Silicon-Fastener-Fitbit-Wristband/dp/B00L7TOUYU/ref=sr_1_9?ie=UTF8&qid=1430793202&sr=8-9&keywords=fitbit+accessories

**Q: does it have a clock**
A: No. there is no face on the fitbit.  It is completely blank unless you tap it to see your activity progress which shows up as little lights.

**Q: isn't there a recall on the FitBit**
A: The newest model is called The a Force and it has been recalled because the clasp contains a metal that creates a rash on the arm of the wearer.  I have the Fex and the One which are older models which have not had any problems.  The Force is not for sale now and it has been recalled by the manufacturer.

**Q: does this come with the charger cable included?**
A: Yes it comes with a small band, large band, clasp, charger cable, and USB sync dongle.
