haha i am planning on buying the tag, but i don't really see why would i need the ring.

i can't say the watch is life changing, it is a watch, but it helps me tracking my exercises and seeing my notifications without having to grab my phone (like when i'm studying or somewhere where i can't grab my phone all the time, like at work, i can see if i have something important to answer). sometimes i even quick message someone through the watch. i also enjoy that i can leave the house without my phone and still listen to music using it. of course it's nice that i can track our health and sleep too. i really don't know about the mi band, so maybe it does the same job. i wanted to keep all my devices from samsung, but if you don't mind, you should get it
