" ... This band is working like a charm for most of the features. ... "
" ... You really can't beat this band for the price. ... "
" ... Most accurate fitness band under 50$ that I ever had. ... "
" ... Love this little band! ... "
" ... The band is amazing. ... "

" ... And the battery life on this thing is outstanding! ... "
" ... Really liking how long the battery lasts. ... "
" ... It's not a full fledged smart watch, but it's $30 and the battery lasts for weeks. ... "
" ... Battery life: very long, long enough for anyone with reasonable expectations out of a wireless mobile device ... "

" ... App: Just awful, the app is buggy and requires too much personal information, gets you a little on edge about CCP surveillance ... "
" ... App doesn't sync well with the watch. ... There were days when my watch would have many more steps but the app wouldn't sync and update the number. ... And finally one day I was up to see sunrise at 5.30 and at 6.08 am the app said that I woke up at 6.30 that day. ... "
" ... Now, the app doesn't record my history. ... :( Very disappointed in the experience I've had with the mifit 4 and if the app doesn't get fixed soon, I will be looking elsewhere. ... "
" ... The interface of the app is messy and confusing. ... "
" ... On the alerts & notifications side of the band, it works, you receive notifications from the apps that you tell it to, and you can also control spotify with it, so it's a cool plus when you're running, there are videos on youtube that show you how to setup an app that will mirror your phone screen on the band's tiny screen, but I don't see the point of it, maybe to check on something specific that the band can't tell you. ...

" ... The heart rate and step tracking encourage me to do more outdoor activities. ... "

" ... But it have an awesome battery life and is really good counting steps and the heart beat measure is also good. ... "
" ... Measured heart rate is not accurate comparing to Polar Chest belt type. ... Chest belt type is exact beats as actual heart rate. ... "
" ... I'm very happy with this smart band the only down side is the step, sleep and heart rate seem to be a little inaccurate but not by much at all. ... "
" ... on the other hand, the heart rate seems very accurate and the sleep tracking also seems ok, so at least that seems to be working fine. ... "

" ... Bought this for my 83 year old mother to track her steps. ... "
" ... Most accurate fitness band under 50$ that I ever had. ... "
" ... So I originally purchased "the OTHER fitness tracker" but returned it because it was not accurate at all and was absolutely over reporting my steps. ...

Some time I would like to go back and compare with other days by checking to see if i did more or less steps with that exercise or my average heart rate,, but I can't. ... "
