Hi
I bought my 1st fitbit charge2 a week ago. Before I purchased it, I asked my co-workers (which they own the charge hr & alta) how they like theirs and if they have any issues with it. With their reviews, I decided to purchase one for myself. Well…my first use of the charge 2 was Saturday evening; the accuracy was I guess ok (since it was only for a few hours). I wore it to bed to check out the sleep tracking feature and I guess I found it “eh”. I don’t think I’ll use it to sleep as often. I do like the pulse monitor though. For the next few days, I was monitoring it and noticed that it was adding steps when I was getting dressed, combing my hair, hand movements (I talk with my hands). I work at a desk and do a lot of paperwork/order entry and noticed it was giving me steps for that as well 😕 It’s set to remind me to walk 250 steps an hour. But since it gives me steps while at my desk, sometimes it won’t remind me because it already tracked that I already did the steps or have only a few steps to go (e.i. 50 or 75). I go up the stairs at work a few times a day and for some reason it tracked that I went up 12 times, which I actually went up 5 times. I reset it by charging it and pressing the side button. I even tried setting it to my dominant hand but wear it on my non-dominant and vice versa. I have a pedometer and I at times compare it to it, but of course I know it’s going to be off a few hundreds if anything. But not the charge 2, it’s off by almost 2,000 steps! I can understand a few hundreds, but thousands? How am I going to know if I’m accomplishing my goal if it’s off by thousands? I’m even logging in the driving because it gives me steps (not much though) for that as well. I guess when I turn the wheel, signaling, changing the station, etc. I bought this tracker because I sometimes forget to clip my pedometer on, misplaced it one time & thought it would be easier just to have a wrist one instead. Also I wanted to see if I was getting a good amount of steps in a day, since I have to walk a lot do to a leg procedure I had done. And so it can remind me to move when I’m not moving do to my desk work. Also, I joined a gym and wanted to track my progress and weigh loss. Maybe I bought a defective charge 2 or the firmware is not working on this one? Does the charge 2 or any tracker for that matter get to know the person who’s wearing it? Would it eventually become a bit more accurate within time? I know trackers are not 100% accurate. I'm thinking on returning this one & just sticking to my pocket pedometer.
