      Comments about Fitbit Flex™ Wireless Activity and Sleep Wristband (Black):

      I purchased the Fitbit Flex for myself after hearing great things from friends. I have now had it a month and absolutely love it! It took a week or two to get used to wearing it all the time. I do not wear it in the shower, even though you are supposed to be able to, I just dont want to risk ruining it. I have synched the MyFitnessPal app to my Fitbit Flex and love how accurate everything is. If you are thinking about buying this, I say GO FOR IT!

                I received it as a gift and really love it. It sincs with my phone and iPad, so I can check in on my activity during the day. It keeps me focused on moving to get in my steps for the day! I love the fact that you can also set reminder alarms to go off. As a teacher, that is invaluable to me! I haven't had any problems with my fitbit, and would highly recommend it!

                    I received this as a christmas gift, set up on my desktop, phone and i pad were super easy.
                    Have had it for 12 days and lost 6 lbs, i spend a lot of time working on the computer, and this holds me accountable to get in my daily walks, i log my food and water intake.
                    Most interesting was my sleep log, apparently i still sleepwalk !!
                    I'm very happy with my FitBit so far and highly recommend it !

                          I'm very disappointed with this wristband. It will not sync. It's very difficult to use and I would love a refund. Do not waste your time or money.

                                    I love my fitbit. I find myself at the end of a lazy day checking my steps and realizing I have hardly moved. Most of the time I get up and at least go for a walk, but it is always eye opening. This type of device really helps you understand your behavior and track it. The only thing I hate is removing it to charge the battery. If I charge over night I don't get to see my sleep pattern and I hate to miss a single step during the day.
