3/31/19 I've had this thing for less than a week so I'm still on my honeymoon. Here are my first impressions: It seems to work as intended. If someone just wants to run around the neighborhood, this is perfect. He meticulously counts "every breath, every move you make, every bond you break, every step you take." Heart rate readings are consistent with other devices I own. I immediately noticed that it doesn't count steps, but hand movements and converts them into steps using a complex algorithm. First, I spent two days spreading mulch from my truck and walked 14,000 steps every day! Well, he counted each fork in four steps: put the fork in the mulch, out of the mulch, in the wheelbarrow. In fact, pushing the car in and out counted as zero no matter how far I drove since my arms didn't swing. Then a few more steps to unload the wheelbarrow and lay out the mulch. The next day I hit the gym (as if my poor old body hadn't suffered enough already). Then I realized that ten "flights" on the ladder machine are counted as zero, since the arms don't swing and the altitude doesn't change. My guess is that the rowing machine and elliptical add "strides" but the treadmill and stationary bike don't. I took more steps loading and unloading barbells than squats or bench presses. A little research on the internet showed me that strength training burns very few calories. Something to do with kilograms and meters and joules, oh my god. The free Android app gives me some cool charts and graphs, but there doesn't seem to be a way to fit all that sterling work into my daily totals other than just calories. It shows my VO2 (shampoo?) and tells me I'm in pretty good shape for an old man. The free Fitbit Coach app seems stuck in the isometric age and as such doesn't allow you to enter your strength training results. It prevented me from entering food consumption data, but it didn't offer a way to turn cookies into calories, so to speak. I checked Revain's reviews and found that the third-party app MyFitnessPal connects to Fitbit and makes entering food calories easier. • I like how Fitbit tells me the time when I look at it, even though I sometimes have to tap it a few times. often to get his attention • It looks good on my wrist • I can set the tempo length or have it automatically detected • The stopwatch function works well and is easier to use than the app on my smartphone. • The sleep monitor also works properly; to give me information that I already knew and that didn't particularly interest me. This can come in handy when someone has trouble sleeping. • I haven't tried all the notification features like email and probably won't. • I haven't tried walking around the neighborhood either, as it's not part of my workout routine - yet • It pairs seamlessly with its own Android phone app and the MyFitnessPal app. I bought the Fitbit Charge 2 because some Revain reviewers said it was better than the Charge 3. I also bought a three-year protection plan, which I rarely do since reviewers said the device sometimes fails after sixteen months. We'll wait and see what comes of it. I give five stars because of the cheap price and because it works as expected. Time will tell its reliability.
