The Force is a wrist based fitness tracking, that tracks steps, stairs, distance and estimates calories. And it has a liitle screen to display your results or act as a watch (though you wear it on your dominant yand, so it is on my right wrist instead of left, which takes some gettimg used to). The Force is my third Fitbit product, I had an original fitbit which I washed and a Fitbit One which had it's battery die, and support never repplied to me to get it fixed. And now my dad who gave me this also gave me the awesome wifi fitbit Aria scale to track weight. The Flex is a decent fitness tracker, though has some serious issues, the first of which is the strap!Instead of a normal watch band that would stay on, you press it this together to hold it on, but it does not stay on. It falls off me at least once a day. And even went into the toilet once, and it is only splash resistant (not a good thing for something you wear all the time like a watch), though I saved it. And it comes off almost every night while I sleep, which does not help the sleep tracking. Fitbit tried to re-invent the watch band and failed miserably! A normal watch band would have earned this aa great review, but I have not even had this a month and am sure I will lose it soon!The two metal pieces that fit into the watch band holes.Snapped together, though not very well.And the stair tracking is flawed at best. It doesn't track going down stairs at all, and you have to really be swinging your arm for it to track while going up. I was holding my iphone while going up 8 flights and it only registered 3 flights, though it normally registers 8, which is just annoying.Another complaint is that it has lost some functionality. The original FitBit and the One both had a fun little flower you grew based on your daily exercise. Useless but fun, but this is gone from the Force.And while it does a pretty good of tracking even without arm swing, it does register steps where you don't get them, like raking or working in the yard, which is kind if a cheat, but expected because it is on your wrist. I do like it on your wrist as you don't forget it.Battery life seems pretty goid, lasting a good week, even when bluetooth synced to my iphone for syncing, and only takes an hour and a half to charge.A decent tracker, but they really need to put a normal watch strap clasp on it, so it doesn't come off so easily, and water proofing would be nice too!And i do think fitness trackers are great as you dp push yourself more because of it. I park further away, or go up more stairs because of the tracker, and wanting to do better. And seeing…
