providing you don’t have any great expectations of it, they’re OK.
I use mine as a silent alarm, nothing more. bluetooth connectivity allows me to see texts on my wrist, and play music from my phone to the crappy speaker in the watch. quite why I’d do that I don’t know.
I can call from it too, and the person I call can hear me, if I speak into the watch. but that makes me look like I’ve got some 1980’s spy tech. still, it beats what most 20 somethings seem to do, having a call on speakerphone whilst holding the handset flat in front of their mouths. it’s not friggin star trek.
