Review: Discrete, pretty, and motivating! - Okay, so I didn't think I would love this as much as I do. I'm not a very "fit" person - I don't go to the gym as a hobby, I don't count calories, I don't drink protein shakes, etc. - so I thought I wouldn't get very much use out of it. However! I use this thing all the time, and it even motivates me to keep moving! I love that you can set your own goals, too. I run three times a week, and it recognizes that as my goal. It's interesting how it keeps track of your sleep, too. The battery charge doesn't last for very long, but I think it charges fairly quickly. I usually just charge it when I'm sitting down to watch TV or something when I won't lose any tracked steps. If you're on the fence about this, I would say go for it! It's the cheapest one and it isn't super bulky. It's very discrete, so it doesn't look so out of place when you have to be dressy, which is something I don't like about the Apple watch or some of the more intense Fitbits. *UPDATE* so like three days after posting this review, my dog ended up chewing my Fitbit while it was charging. I contacted their customer service and explained the situation and told them I've had it for less than two weeks, and despite dog chews not covered under the 1-year warranty, they replaced my tracker for free. I'm actually amazed by their customer service. I contacted them late Saturday night, and by Tuesday morning my new replacement tracker is preparing to ship. Just wanted to share how insanely helpful the Fitbit customer service is.
Review: Great product - This was a great product... Lasted well... Did what it was supposed to ... Passed it on to hubby when I got a newer one and it lasted him a while too

## Questions & Answers

**Q: Does this actually have a tracker in it? I bought a 100$ bangle that did not have a tracker!**
A: Yes, it has the tracker in it. It also includes the charging thing for the tracker and two different sized bands, which are small and large.

**Q: I have large wrists. What is the largest wrist that it will fit?**
A: It will fit up to a 9 inch wrist

**Q: Why does the fitbit 2 not recognize bluetooth? and otherwise, why did it not come with a dongle? also, define dongle for me. i dare you.**
A: It does recognize Bluetooth just fine. Go through the steps described in the manual to establish Bluetooth connection. The wireless sync dongle is the small USB device that comes with some Fitbit trackers. The dongle allows your tracker and computer to communicate with one another. You don't need it if you're using mobile devices, only for computers.

**Q: Is the charger necessary? Is the battery rechargable?**
A: Yes, the charger is necessary. The battery is a small rectangle box like piece that requires charging periodically.

### ⭐⭐⭐⭐⭐ Great product

### ⭐ This stupid thing is garbage
*by A***A on December 14, 2018*

I have had this fitbit for over a year, and I wish I hadn't wasted my money on it. It will randomly just stop working and not track anything at all. When it is tracking, it does not keep track of any exercise aside from walking accurately at all. For example if I bike two and from work which is 11 miles I don't even hit my steps for the day, but if I stand in one place and scrape paint for an hour it says I hit my steps. If I do an hour of yoga it doesn't register any of that. I'm sick of tinkering with the dumb thing to get it to sync with my phone and make sure it's actually working. The food log is clunky and way less user friendly than my fitness pal which is annoying because then I have to go into two different apps if I want to log calories. It's supposed to be a handy tool to help make life easier but it's actually just a pain in my rear and I'm through with it.
