Great watch!

i bought this watch on a whim. my health hasn't been great and i seen this and bought it for the features. it can detect sleep apnea, it will send out a SOS alert if you fall, it tracks ur heart and oxygen and can even run a EKG. i have had it for months now -6 mo or so, and have not used even half its features yet! i love i can answer my phone thru the watch if my phone is not within reach. cute pink band. sending messages is hard bc its so little cute possible lol. i did notice it disconnects a lot for some reason. battery stays charged for 1 day. charging only takes 30 min to full.

All around very functional and does what i need.

works very good, after the first day or two of getting set up and used to the battery seems to have adjusted and will last about a day and a half to two days, adaptive brightness works good, messaging works surprisingly well, tap to pay works good even using google wallet, nice features and very customizable with the watch screen, I really love being able to add custom photos or gifs. only gripe is at the time i had to get this one and not the 6 as they were sold out with the 6 being the same price.
