Pluses first, cuz I'm a positive kinda guy. Basic function works fine. It's portable, immersible, and so far has stayed on when I put it on.BUTI had to get the charger replaced after about 3 months.The band split where rubber meets the LED window. Had to get that replaced after 6 months.The new charger needs help to get electricity to the cartridge. Cartridge snaps in place and stays there OK, but apparently not with enough force to make good electrical contact. As a workaround, I used folded up paper as a little wedge to force the cartridge onto the contacts more firmly. Also, I clean contacts with rubbing alcohol.Step count is greatly exaggerated, by as much as 20% sometimes.Lastly, the customer service flow needs work. The reps are courteous (as well as can be judged in email threads), but the process is a pain. Open a ticket, get an email, reply to email with picture (of a cartridge NOT charging or a broken wristband). If there was a way to upload the picture when first opening the ticket, I didn't see it. And furthermore - it's a USB charger! or It's a wristband! Just take my word for it and send a replacement. All these extra steps are costing them labor and me patience, with no value added. If I was asking for a new cartridge, maybe then some evidence is warranted.

For the most part, FitBit us wonderful! It's easy to wear. However, after three months it won't charge anymore.

The Fitbit Flex has become my quadruple-check item. Wallet. Keys. Phone--Flex. The product is unparalleled in the wearables space and so is Fitbit's customer service. I lost my Flex in the first week and Fitbit sent me a replacement, no questions asked. They were even able to track down my lost Flex a few weeks later and sent that to me as well. Given my penchant for losing things, I'd love if the Flex had GPS. But overall I've been thoroughly impressed and satisfied as a customer.

A great device overall. Just a pity that, like all it's other cousins from other brands, it's not as accurate as the ideal user would hope. But overall great design, intuitive usage, a sexy accessory and a very good night time companion. It's fascinating disseminating my sleeping patterns. I can tell exactly when I'm having a bad night's sleep due to stress or whatever. Great product!

If you are looking for accuracy, this is NOT. the right choice. The step and other measurements are way off. It counts steps when I am sleeping. Tried support but all they they could say it is motion based, basically admitting that it would not be accurate. wish I had bought another brand.
