I love my Fitbit Alta HR! It even alerts me to phone calls and text messages. It is the easiest and quickest Fitbit to charge. The battery usually lasts 3 days. You can change the bands. The display can be set to read vertically or horizontally.

Started out with a Flex, and upgraded to the Charge HR & then to the Blaze. Really happy to have a smaller watch that includes the features I want & like. Very happy with all Fit Bits, but especially pleased with this model.

So far so good on my new Fitbit HR! I’m loving it! It definitely makes me move a lot more than before! I also love the PurePulse feature and the sleep pattern features!

I absolutely love my Fitbit Alta HR! The only thing I’d have to actually say negative about it is it sometimes cheats you out of steps. But that’s a good thing! So far I’ve put over 30 miles on it in less than a month! Yay!!! I love the all the features too!

It's been only a few days since I had this; however it does pretty good job of tracking your activity. There are indeed some miscalculations; however it is acceptable as far as I am concern. I had hugely debated between this and Charge 2, since I didn't find Charge 2 too big for my wrist. But far less obtrusive design of Heart sensor (IMO) on this Alta HR fixed the deal. Charge 2's heart sensor was pretty uncomfortable for me. I do sweat a lot thus I tend to rinse it right after the workout and thoroughly dry it. So far it seems okay, and hopefully it's water resistance would keep it that way. Oh BTW, it's pretty difficult to read the measurement on a bright sunny day. So if you frequently check while you workout outside, you might want to choose different one. Also if you are an avid tracker with quite fine measurement requirement, I don't think this device would satisfy your needs; however if you are okay with a few miscalculations/errors here and there then this should work well for you as it did for me.
