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.

In love

I love this watch. I wear it everyday to work. I like the power saving option because the battery lasts me all day. I can call and control my music from the watch, so that's a plus for me. I have a small wrist, and the band that the watch comes with makes my wrist look funny, so I bought a band online. I like that we can customize the watch.
