Update after 32 days of use:
Notifications:
* The duplicate notifications for Bitcointalk/Telegram no longer happen that often, especially after the last update of Xiaomi Wear app
* More annoying "duplication" of notifications happen with the e-mails (they keep coming until I remove the notification from the phone)
* All in all, it looks to be a bunch of bugs in Xiaomi Wear app, not with the bot or the other apps
Overall use:
* I like its faces and colors, you can play with them, but still the default few ones are easier to read (+)
* The transfer of data between the smart band and wear app is slooooow and only happens if you open the app (look into it). (-)
* Continuous hearth rate check is interesting to have, but unfortunately blood pressure check is missing.
* The battery lasts some 6 days, but I usually charge after kinda 5 days already
From a band 3 I've seen, the step forward is clearly noticeable, but I cannot tell that it's
big... It's just a smart band after all
PS. SPO2 is "on demand" and I've used it some 5 times all together. Didn't look too accurate either...
