Review: You can see why so many people own one - I have only had this a few days now but these are my initial impressions: You have to wear it on your wrist (duh) but that means comfort is important. Its superbly comfortable to the point I no longer think about it. Functionality, it seems to be very good. The distances seem about right and it is already motivating me to get out to meet or exceed my target, something I would never have done on my own. The software, very good. I have mine on an IMac, an Android phone and a Chrome OS laptop (doesn't support the dongle). I can sync using the Imac with the dongle attached and with my phone via bluetooth or NFC, both work fine. I can only view and not sync with the Chromebook but this is not a problem because I always have my phone with me. My wife only has her phone and Chromebook so can't use the dongle. Syncing with her phone is fine and as a minimum this is all you need. Battery life so far seems very good, I am into my first week and have only charged on day one and that's with a daily alarm. The alarm is really good and has a snooze if you read the instructions, you can set it for a one off or repeat for various days of the week or weekend. No need for anything else now. My only question is how it deals with changes to and from BST, don't know, I will have to find out. Worse case scenario is I set a phone alarm twice a year. I have the black one and have a very conservative job, I don't think it looks out of place and only one person (who wants to buy one) seems to have noticed it. Hitting your daily target at unexpected times still makes me jump and on one occasion some one said 'Are you ok?' so I had to explain lol. I'm sure I will get used to it. Changing all of the settings is easy and intuitive and all in all once you have set it up you can just forget about it apart from the occasional sync so you can see how you are doing. I like the sleep setting but it tends to tell you what you already know, I had a rubbish night's sleep or I had a good night's sleep. There have been some comments about durability of the strap but only time will tell. I will report back in time. Spare straps seem to be widely available and with a whole range of colours. After a week of ownership I would say get one.
Review: I had always thought that as part of my job means a lot of movement and lifting that I should be pretty fit, now I know why I wa - I have have been wearing my fitbit 15 full days and have lost 7lb already! I had always thought that as part of my job means a lot of movement and lifting that I should be pretty fit, now I know why I wasn't! I have mine set to 10000 steps per day, pretty shocked to find that I maybe only do 4000 to 5000 steps a day so it is clear that I need more excercise, the tracker has made sure that I have done this extra excercise, not every day but some days I will do more steps to even it out. walking up and down the house at 11pm at night just to get those 10000 steps is now a must! As it tracks my sleep, and I don't bother to tap it into sleep mode, it still records, not surprised at how many times I wake up in the night, though if I am stillin bed I can still be awake and it states that I am asleep, so not 100% accurate but not bad. It only seems to give me 1120 cals to eat per day which for me seems low especially as I selected that I only wanted a 1.5 LB loss per week, however, the more steps I do, the more cals it adds on for me. Some of the registered foods and the cal value is a little wrong but you can add your own. I realised that my endless cups of coffee through the day were serioulsy zapping my cals, tea uses up much less. And so logging everything that I eat really makes a difference, most days I have some cals left over - allows for a small treat once a week so that I am not feeling deprived. One thing that i was shocked at was the kind of excercise I am getting, mostly light and so i have been really pushing myself to get moderate and was really pleased when i managed some intense excercise, it really is an insentive to carry on. I tend to knock mine a lot andthe lights start to flash, I have no idea really what they all mean, but it still works, it doesn't seem to buzz like it is supposed to but it still works. And so this bit of kit really does encourage you to stay on track with excercise and diet and is the best diet aid that I have ever used, better than a gym membership and diet clubs. Worth every penny!

### ⭐⭐⭐⭐ Pretty good and USEFUL device
*by I***N on 15 October 2014*

We've had this now for 5 months and I have to say it's a nice device. I purchased this primarily for my wife to track her sleep as she was always tired. The fitbit flex consists of two parts; a strap and the fitbit which slips into it. The flex is like a tiny spaceage capsule with tiny lights to indicate things like charging, your mode (daytime or sleep), and how far you are through your 10,000 daily steps. To get the fitbit up and running you have to create an account on fitbit.com and then assign your flex to that account. You can do this on any device that supports low-power bluetooth (for example the iphone 4s and above or ipad 3 and above). We had an ipad 2, so had to use our laptop with the fitbit provided bluetooth USB dongle. The process of assigning your fitbit to your account is simple, and from that point all you have to do is regular internet sync to get the data off the flex and into your fitbit.com account. For the first few weeks in using a flex just accept that you'll be syncing after every bout of exercise and taking a peek at your fitbit.com account stats. It's cool, but happily the novelty does wear off and in time you might be able to wean yourself to stat checking just twice a week. Good things about the flex: 1) Easy process to setup and sync 2) Good battery (we find it's about 7 days) 3) Very comfortable band (you don't know you're wearing it) 4) Website overview of your activity nice (daytime and sleep) Things that could be improved are, 1) The device only holds 7 days of data. This was a pity when we were on holiday and had no access to the internet for a sync. When we got back home and sync'd we'd lost the first week of data. 2) The bands could be more robust. Ours split after a few months (but contacting fitbit directly got us a speedy replacement) 3) Battery level indicator only available online and limited to the battery level at last sync. This is a problem for us as we've no native low-power bluetooth devices so syncing required a little extra effort (and for us can't be done on the move). 4) I really wish fitbit didn't use the "Tracker" terminology when referring to the device. My wife at first thought I was actually *tracking* her which made for an uncomfortable conversation. In summary, it's been a very successful device for us and support from fitbit has been excellent. Turned out my lady was getting sometimes just 2hrs proper sleep a night (compared to my 7 as measured by the fitbit!) which allowed us to trial a few lifestyle changes to see how we could improve that.
