The main reason I bought this is for the fitness tracking. Which work perfect for what I need. I paired the Mi Band 4 with the Google Fit app and it tracks my runs really well. That part has exceeded my expectation. I will say though, that it doesn't track my steps very accurately. For example, a 50 mile drive to and from work will result in about 200-350 steps each way.
A major benefit I wasn't expecting from wearing this watch was receiving notifications from my phone. I no longer have to keep my phone right next to me at work - which can be very distracting - I can keep it behind me or in my bag and see what I really need to see. If a text comes through that I don't need to respond to, I can see it and know that it's there for later. It's really increased my productivity.
One more thing is the alarm feature. I no longer have to have a loud alarm by my bedside. I can simply wear my watch to sleep and it will vibrate whenever I set the alarm for. It wakes me up, but not my partner or my dogs like an alarm does...
I have more great things to say about it, but this review would be too long.
Cons: sleep tracking. I'm pretty tech savvy, but I cannot figure out how to make it work.
