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.

Tricky install but Genius level watch

IMPORTANT in order to sync to your phone you have to cancel your screen lock for the account linking step or google play will just crash and it won't finish the startup process!!! no one seemed to know about this and i went through sooo much suffering getting it to work. the watch is amazing and doesn't irritate my way too sensitive skin. i recommend one of those stretchy fabric wrist bands to go with it. this has become my new electronic baby
