So my sister got me this little do-dad for my birthday and I figured it's a great christmas gift, so why not do a review on it! My sister has had some trouble losing her fit bits before, so she got this for me specifically because it has a big watchband on it. I find this really convenient too. I like having a clock and being able to check the date as well as just having my steps right at my fingertips. I think that you can buy bands to go with other designs of the fitbit... but this one is just an all in one thing that is easy to use... and works really well. This holds a charge better than I expected it too... but probably not as well as some of the other fit bits. I charge this like every 3 days. It has a heart rate monitor on it and little lights that always show up cause those help read your heart rate. It shows up in the dark as well... so keep that in mind. You can turn off the heart rate monitor... but I'm always afraid I'm going to have a heart attack or someth...
