    Works great! It's super light and holds a charge for a couple of days which is nice.

    Fun gadget but not accurate

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    It's a fun gadget but not really accurate. I happened to have my IPad up with the FitBit dashboard open and I noticed it logging steps when I was only standing there folding towels. It's fun and if you're dedicated it might keep you mindful, but it won't turn out to be as useful as you will have hoped.

    I've been wearing the FitBit Flex for about 3 weeks now and I love it! I was doing a comparison between this one and the Jawbone Up. I ultimately decided to go with the Flex because: 1# wireless sync 2# confidence that it wouldn't fall off during the day or in my sleep & 3) tap on the band to see your daily progress. I do think that the Up has a more robust interface #like when tracking sleep the Up tracks deep sleep #REM) vs. light sleep. The Flex tracks Asleep, Restless and Awake. It is fine though and so interesting to view. A big complaint I heard about the flex was getting it off and on. The first 2-3 times it was difficult but now it snaps right into place with ease. The black band does get a little scuffed up and I can't wait to get the accessory bands! They are on backorder for a while. I am also tracking my calories/food through My Fitness Pal and it syncs nicely. I love it!

    Amazing product and app. Very simple to use

    I lost my Fitbit after only having it for a week, I went through every step to find it because Geek Squad did not cover lost or theft, but FitBit replaced my product free of charge. Their customer service is outstanding, they were kind and quick in manner, not only is this product live changing when used to its full potential, the company is worth giving your business to.

    I have had mine for three weeks now and I am very happy with it. I wear it on my non dominant wrist but put online that it is on my dominant wrist(as I am on my computer and move my arms often to do cook and clean and play games) and the steps are very accurate. The sleep monitor it has is more accurate than the iphone apps that I've used and more comfortable than putting my phone under my pillow. I also love the silent alarms and use two for morning and night medication reminders and I have one for the morning during the weekdays to wake me up. The battery on mine lasts for about 6-7 days at a time. I love the Fitbit Flex and I am so glad that I bought it.

    Bought this for myself

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Bought this for myself, because I needed something to help me lose weight, but I wanted to keep my spending down. (My sister-in-law has a FitBit1, loves it, and highly recommended my purchasing one to.) After a week, I surprised myself by not enjoying the FitBit1... so, after some online investigating (reading others reviews of varied fitbits) I opted to return it and pay a bit more to get the FitBit2....and I Absolutely Love It!! I have no regrets here what so ever with my choice... I love the time and step display, the stop watch, and ect all at a touch and at any time of the day :D Thank you Best Buy for your awesome return policy "...If you are not fully satisfied with your purchase, let us help you with a replacement, return or repair." :) !

    Does the job

    This is the new flex fit bit. Its very simple to wear and use. I am not sure why others are having problems with the unit. Mine worked out of the box. I use an Apple MacBook Air and have an Apple Iphone 5. So far, no issues at all. I will report back if there is an issue. For now it gets my 5 stars.

    Worked, but returned

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    It worked and I loved the functionality, but I returned it because the upcoming "trend" of smartwatches replaces the Fitbit in most cases in my opinion.

    This is great for a beginner, but there are better options out there. Wish I would have got the upgraded version showing the time on there.

    Comfortable and functional

    My only complaint is that i wish it calculated my indoor and outdoor cycling automatically. I do have the ability to "log" this activity into my dashboard which is fine, it just takes more time. Had the NIKE one and disliked it completely.

    Fitbit flex

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I do t see the force being worth the extra money unless you need the time. The bands should be sold separately in black. It doesn't wake you up at your optimal time the way the up does but it's the best tracker for the money available. It's very dependable and doesn't need to charge but once a week and the app is very intuitive and simple. Recommend

    I enjoyed this, but the charging system failed fairly quickly, and it would be nice to know actual values instead of % based on lights. also went into sleep mode on bike rides due to vibration. Upgraded to the charge HR - digital readout is worth the money.

    I've used this for 2 weeks now, and have become very aware of how inactive I've been. I have a desk job, and push now to walk 10K steps daily. I've downloaded the FitBit app to my iPod touch 5, and it syncs via Bluetooth. I'm always up to date on logging my calories consumed, and calories burned. This also tracks my sleep patterns which is very interesting information.
