Pros-
HUGE battery life - close to 30 days
GPS
App Notifications
Supports ios and android
Number of watch face
Right size and good design

Cons-
Cannot receive the calls ( though you can disconnect the calls through the watch)
Not a smart watch

the watch is great and have found no problems with it at all except every now and then I forget to take it of at night because I feel that I could damage it but fantastic wearable good looking and style amazing

I don’t know many runners that don’t use Strava, the recommended mi fit app will not let you upload to Strava. The only way you can is to find an alternative app and then In my case I lost accuracy in time and an inability to track heart rate.
If this is not a problem to you then it’s pretty good, in my case it’s bit of a let down.
I can’t imagine why they don’t make this easier, it’s a no brainer.

I have had the Amazfit Bip for a couple of months and was quite happy with it. Then suddenly, it hung on the Activity screen with a 'Suspended' message. I tried to revive it with everything but the kitchen sink, looking up the problem on the Net, pressing button a million times - nothing would bring the watch back to life. Only by letting the battery run flat - it took two days - could I get the watch working again. That's not good enough for an everyday item . A simple reset button/utility would have solved the problem.....

It's no Apple watch but for the price and the purposes I have for it, it's perfect.
I still can't get over how the battery lasts a whole month. Monitors fitness when you turn it on and counts steps continuously. I would recommend purchasing a custom band for it as the rubber one might not look very good.

I bought this as cheap entry level fitness watch from Xiaomi only pros is goood battery life apart that there is lot of syncing issues and I guess you get what you pay for I got the watch from Kogan for $100. So cant complain its has hear rate monitor and also ability to track your sleep

I bought my Bip 3 months ago from Kogan and at first I was bit ho hum about it, but switching to the Notify and Fitness app instead of the standard Amazfit app my opinion has been increased 10 fold. I found a much better custom watch face and it works well with my phone. The battery lasts a month and the reminders and updates work really well.
The heart rate sensor is fairly inaccurate and the included watch faces are poor but there is a huge online following with 100's of free custom mods and watch faces to try.

Tracks activities on the watch then won't sync them with the phone. Known product issue but no action being taken by Amazfit.
UI incredibly laggy. Selecting a menu item results in an 8 second wait for that section to open.
Sometimes doesn't vibrate for notifications.
It's cheap and behaves accordingly. Save your money and buy a quality product instead.
