How do I charge my flex?
Your tracker battery lasts for about 5 days. To charge it, remove the tracker from the band and place it in the charger until all 5 lights are solid.
If you are having trouble, your tracker's charging contacts may be obstructed by microscopic dirt or debris that prevents them from making a good connection to the charger. Use hand sanitizer and a tissue or dampen a cotton swab with rubbing alcohol and carefully clean the charging contacts on your tracker. Do not submerge your tracker in water or use abrasive cleaners. Thoroughly dry your tracker before attempting to charge. Be sure to fully seat your tracker into the charger, with the charging contacts fully inserted into the charging cable enclosure.
How do I reset my tracker?
lf your tracker is not responding, it may be fixed by restarting.
1. Plug your charging cable into the USB port and insert your tracker into the charging cable.
2. Insert a paperclip into the small pinhole on the back of the charger.
3. Press on the pinhole for 3-4 seconds.
Your Flex will now be reset. Take your tracker out of the charger and insert it back into the wristband.
Can the wristband irritate my skin?
The Flex wristband is made of a flexible, durable elastomer material similar to that used in many sports watches. It does not contain latex. The clasp is made of surgical-grade stainless steel and contains traces of nickel. As with any type of jewelry, some people may experience allergies. Numerous factors can cause an allergy, such as a nickel sensitivity, reactions to bacteria that can accumulate in watch wristbands or other wearable devices, a reaction between the wristband and your soap or perspiration, or an allergy to the material of the wristband. If you notice any signs of skin irritation or experience any discomfort, please discontinue use.

The update took about 5 minutes using my iPad and plugging my Fitbit into its charger while it updated. The whole thing was simple. A red arrow on the dashboard, in the sync area alerted me to the upgrade. I really like this new feature.
I bought 3 of these fitbit flex devices, one for myself, my husband and my sister. Before purchasing I researched several wristband devices such as the Jawbone UP, the Nike Fuel and and the Polar Loop. I also looked at the fitbit force which is a newer version of this band. The lack of water resistance on the force was a deal breaker for me. I wanted to be able to wear this band 24/7 and to be able to wear it in the shower or when swimming. That was part of what made it attractive to me. Also, after reading reviews about the clasp problems on the force and how many people lost them, I wanted no part of that. They are also quite a bit bigger and look clunckier. The wristband on the UP looked like it would catch on everything and had no display at all. The Polar had lots of quality problems. I wasn't crazy about the looks of the Nike. The display is nice and I can see how people would like them, but not my style. The fitbit flex, to my tastes, had the coolest look.Read more ›
UPDATE: I uploaded several head-to-head app screenshots.
UPDATE: I've found that I am storing quite a bit of water in the Flex band pouch where the module goes. Even though they say it's shower safe, I'm pretty sure some funky stuff is going to be growing in there in a matter of time... But the band is replaceable!
My journey with personal monitoring devices/pedometers started a LONG time ago: Before Fitbit even existed, with a device called the SportBrain. It was a traditional belt clip style so old that it plugged into a base that used a dial in phone modem to upload the usage data to a server. It was old. But my interest in devices that can help monitor and tell me about my activity started then, and we seem to be now in a golden age of personal data monitoring devices. Fitbit Flex, Jawbone UP, all of the Fitbit clip devices and so many more...
The biggest drawbacks I found on the Jawbone UP were that it had no visual feedback about your daily achievement toward your goal and the fact that it had no visual battery indicator. It wasn't a problem for me personally, but for those who are hardcore driven on a daily basis to compare and achieve this could be a drawback for you.Read more ›
I also suggest that you tune out the 5-star "this is AWESOME!" reviewers. I've had the Flex for 6 months now (acquired at CES 2013, long before retail availability) and initially I too was impressed by the technology. However, with long-term use, I think its inaccuracies make it nothing more than a pedometer with sleep analysis added in (and the usefulness of the latter is dubious as well). The IDEA of it all is excellent: to track your activities and see your progress over time via the great software that Fitbit has developed. However, all of this is predicated on the device accurately tracking your movements. If it fails in that aspect - and unfortunately it does, to a moderate degree - then all of the data and impressive charts and graphs are rather useless. The "awesome!" reviewers don't realize this (yet) and just assume what they're seeing is real; it isn't.
The underlying technological problem, as I see it, is in the placement of the tracker. Up until now, Fitbit trackers were to be placed on the torso. Now, it must be placed on the wrist (yes, the tracker itself can be taken out of the wristband and put into your pocket but all of Fitbit's calibrations and algorithms are designed for that wrist placement and you are making the problem worse by not having it on your wrist).Read more ›
