    Just buy a shine

    Very beautiful pink color......however, it looks cheap, and not as sleek as the shine. Also it worked great for 2 weeks, then went haywire. Would work occasionally thru out the day, changed battery, and still acted crazy. I returned it!

    I bought this tracker because it had great reviews and was waterproof. It is not waterproof! If you are buying it for that reason try another product! Other features worked great like syncing with phone and MyFitnessPal.

    Band broke in 3 days

    The band broke on my wrist after only having it 3 days. I was pleased with the overall performance of the tracking features but the band is too flimsy and is easily broken.

    Do Not Use To Swim Laps!

    I bought the Misfit Flash for my son to use for swim team practice. The package said it was waterproof to 30 ATM... He doesn't go deeper than three or four feet. After swimming a 200 yard warm up it stopped responding so he took it off and put it in his pool bag. Several hours later it is still not working. We have only had the tracker two days and will be returning it. It is not water resistant let alone water proof. If you are a swimmer do not buy this item.

    returned it

    It is suppose to track your sleep automatically but if you sleep at odd times of the day, it doesn't. For it to automatically track your sleep, you have to sleep between the hours of 7 pm and 5 am. So I returned it

    Lasted 5 minutes

    I purchased this tracker along with a Jawbone UP2 as they were both on sale. Cnet reviews had them close in performance. Owner reviews were correct in lifespan. BB sales associate told me the Misfits get returned a lot. The Misfit lasted 5 minutes out of the box. The Up2 lasted a week. I returned it.

    The flash is designed so poorly and cheap!! Im so disappointed. It fell off my wrist and I didn't even feel it fall off, the band design is horrible!! Plastic and the disc part barely even fit in the band. I will never buy a misfit flash ever again. Change the design on it!!!!

    Do Not buy this product can't get it to work properly with several different phones (IOS, Android, Windows)... save your pennies and buy something that actually works. This thing just looks like a good deal.

    I was shocked at just how flimsy the unit is. The face did not want to stay in place no matter how hard I tried. Needless to say, I returned the unit the following day. Look elsewhere...

    Stopped working after 3 weeks. Best Buy refused to exchange. Not worth sending in for warranty.
