## 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.

### ⭐⭐⭐⭐⭐ I loved (past tense) the Fitbit Flex 2
*by  on Reviewed in the United States December 13, 2016*

I loved (past tense) the Fitbit Flex 2. Alas. I'd had it exactly one month. I am very sad. It was on my wrist and latched... then the Bermuda Triangle West ate my FitBit.And I am myself, very very lost without it. I'm amazed at how quickly I adapted to it and started upping my activity level. Getting to bed on time more often. And I appreciated the reminders to move around more often when I was working at home on the computer. I had just got two friends to sign up to a challenge -- this is what I have to do to move more!I still have hope it will reappear. If I buy a new one and the old one shows up, I've already decided I can give it to my sister who is disabled and loves to go swimming. She needs one even more than me! And I need one bad! I didn't know how badly until I got one!I charged it late evening Wednesday and put it on when I went to bed. On Thursday from 1:30pm on I was Christmas decorating a local community center. I left about 5pm and a little bit after that, noticed my Flex 2 was not on my wrist.According to the FitBit App it's last sync was Thursday at 2:01pm and the battery was full... It's been a flat line since then. I've stood in every corner and in the middle of the community center and Sync says "Tracker can't be found." If the battery was full - why can't Sync find it? We've scanned the center, the trash cans and pulled bags, the recycling bin, restrooms, closets, under cabinets, etc.- 3 times since Thursday pm. We went through all the empty decoration boxes too. I didn't go outside of the community center between 1:30 and 5pm.I had charged the FitBit on Wednesday and put it back on just before bed.The wristband was on until Thursday ~2pm - so it had to be latched. I didn't notice snagging my wrist and pulling hard - we were just putting out a Chistmas village and making silk flower arrangements. No ladder climbing involved! Several others unloaded the van even!! I'm holding out hope.One thing I had already learned about wearing it: Make sure the band is tight enough that the band won't flip over. I found the Tracker (black and the size of a skinny Chiclet) one morning on the bathroom rug. I had the band on slightly loose and pushed it back to wash my hands. This flipped the wristband wrong side out and the Tracker popped out. So from that day forward I resolved to wear the band snug enough that it wouldn't roll over.Second resolution: Buy it with whichever one of your credit cards covers loss or damage for double the warranty period.Here's hoping you hold on to your's longer than I did mine. All the best! Cynthia

### ⭐⭐⭐⭐⭐ Good for sofa sloths
*by  on Reviewed in the United States December 30, 2017*

I'm lazy, and it shows in my latest lab results from my doctor. I doubt I'll ever be one to so any strenuous exercise, but I've got to step up the activity a little, or I'm headed to an early death. I figure if I can actually see my activity levels, it might be easier to push myself a little further when walking my dog or choosing between the elevator and the stairs. So far, that's exactly what's happening.I'd been eying the Fitbit Flex 2 for a while, and some Amazon gift certificates for Christmas finally made it happen. The price-point is very affordable, and it's mostly waterproof, meaning I won't accidentally kill it by forgetting to take it off when I wash my hands or rinse a dish. And who knows...maybe I'll get a wild hair this summer and make use of the swimming pool.Having never used anything remotely like this before, I was glad the app walked me step-by-step through setting it up. Unfortunately, it just wouldn't connect to my phone after the double-tap thing, but after a little online sleuthing, I found among the similar complaints from other users one comment that said to just keep tapping after it vibrated. And tapping. And tapping. And believe it or not, that did the trick.The app itself is pretty awesome. I loaded it on my iPhone, and it syncs throughout the day, telling me how many steps I've taken and how many calories I've burned (including the ones our body uses just breathing and being alive). I can add things I've eaten, set and track activity and weight goals, and see how well I've been sleeping. I especially love the silent alarm and notification features, since it can (a) quietly alert me to a cell phone call or text message, which is awesome while I'm at work, and (b) silently remind me to get up off my butt and move every so often.Wearing it is surprisingly comfortable. I suppose if you're not used to something on your wrist, it might take some getting used to, but I typically wear a couple of bracelets, so this wasn't really a change for me. The wristband material is flexible and pretty tough, so it can handle the bumbs and scrapes of going about my regular life without damaging the magical pebble inside. I like that it's fairly inconspicuous as well, with no digital face to attract attention. After all, I have my lazy reputation to maintain!So far my activity isn't impressive at all, but at least I can measure what I'm up to, have a concrete starting point, and set a realistic goal. 10k steps? Nope, probably not anytime soon. But 5K would be a huge improvement for a sofa sloth like me, and my dog is loving that I let her take me on longer walks now that I'm able to see my lack of progress -- and finally do something about it!

### ⭐ defective merchandise
*by  on Reviewed in the United States January 3, 2020*

About 9 months ago, I decided to get a new fitbit and saw a sale on Amazon from 1seller1. Having used this product in the past (flex 2 received as a gift and earlier model from Best Buy store) I purchased this new fitbit flex 2 hoping to motivate more walking-instead I've had annoyances and aggravation from trying to get this to work. Essentially it is junk. When it first arrived it would not charge-pretty much not at all.After hours of having it in the outlet charger to no avail I tried the laptop charger. So, I arranged to return it for a refund and received a refund label (so that was good) but since I could not locate the original packaging was unable to do so. I found the packaging later but it was too late. I have no way to contact this seller. Later, I tried again to charge it as I saw one light and had a glimmer of hope it might work. Having thrown away good money on this product, I tried in vain to get it to work. I managed to get it to appear to have charged it minimally to get a flashing blue light and the occasional buzzing. However, as it turned out, that did not mean it would be "findable" by the fitbit app each time. Only once was it-to my phone app-never the window app on my laptop with the non-blue tooth device dongle--but regardless of the perceived small victory, the battery failed to ever charge sufficiently to sync ever. So my conclusion is: this must be a knock off or one of the"made in china" poor quality and defective merchandise units-- in comparing this seller's product to the ones I previously purchased at reputable stores (which actually managed to work all the time unlike this which never worked) I would like to get a refund but won't hold my breath -despite the UCC which requires a refund for defective products within 1 year. That is a huge drawback to buying on Amazon instead of the old fashioned trip to a physical store. BUYER BEWARE.
