Bests & Worsts Reviews from Amazon

I had to give up and return my 2nd unit due to issues. I had screen problems on the first one, and it could have just been the poor tech to begin with. My second on lasted a couple of weeks until it failed. I started getting heart rates of 170 on light workouts, and a full charge couldn't last my entire sleep last night. I would be willing to hold out for some firmware fixes, but I'm not going to get stuck with bad hardware if that's the case. My wife has the non-HR one, and that seems to be fine, so I'm thinking it's the whole heart rate tech that's not ready for prime time here. Either way, I have to give up on it. I'm keeping the original subject and review below so you can see I thought it had promise originally. Apologies to anyone who read that bought one. I would ask you reconsider if you have any issues if you are within the return period. "Screen and charging issues keep a very accurate tracker from being great" Pros: - Very accurate heart monitoring. I use it with a Polar chest strap on a treadmill, and at 140bpm, it's usually within 3-5 beats. Doesn't seem to waver as I start to sweat, and looking back at results, has consistent results over the whole session. - Very good distance tracking. On a treadmill, it was within .1 miles of what the treadmill reported. I'm not always confident the treadmill is getting it right, but they somehow both agree. Even without the GPS, it's distance report for my walk it correct is well. - Auto tracking works well. It doesn't seem to pick up weights or yoga (even past the 10-20 min point), but running and walking are within a few minutes of actual. - Sleep tracking is accurate, at least as far as knowing when I went to bed and got up. I'll have to take its word on REM, etc, without a sleep study, but the times it shows as awake feel right on nights I know I was having problems sleeping. - Good app and website version (starting to hate apps that skimp on the site). Cons: - Screen functionality is garbage. I have motion off, it still finds a way to turn on...at night, all night. I touch it because I want to see it, and it shuts right back off. It's on, but better see what you want to see in that 5 secs before it shuts off. Swiping? Swiper, no swiping without a lot of brain damage. Trying to check things while you're running? You'd get better reactions smashing it against your forehead hoping it gets what you want. They should make it voice activated, because I spend all my time yelling at it anyway. - Charging is sketchy sometimes. Mostly it's fine, but sometimes it seems to sleep the device, and not charge it. - (App) Very flaky connectivity to Google Fit. There's a third party app that will do it for you, but I think it says a lot it needs one to do that lifting. - (Account) Login with Google doesn't work, but maybe it's for the best not having them share your login. My takeaways (so far): - Do not by it as a wrist device, but as an info-gathering device. Using it is a zero, but the data that gets to your account is a five for depth and accuracy (hence the three stars). - I have found manually tracking (on/off) an activity improves the screen sensitivity. Once I started using that, it was possible to touch and swipe a little better. Still, not enough to make the thing work the way it should. - Battery life is probably three days...possibly less, but four would certainly be a stretch. Haven't taken it the distance, and I expect different usage/settings would vary it anyway. I base this currently on being down 20% +/- after various 24hr periods. EDIT: Yesterday it went from full to 14% in a 12hr period, with some recharging during that time, so it's really all over the map.
