The watch is lightweight, reasonably comfortable. It has a camera, voice recorder, audio player, sleep monitor, Pedometer, image viewer, alarm, calendar. Also remote controls for the phone, you can launch the phone camera, take a picture and view on the watch. It has a 32GB SD slot and charges via standard USB port.

The main thing I was looking for was a wearable mp3 player, for listening to books on tape while I'm working in the yard. With a speaker, so I don't need to deal with headphones, and wearable as I can't hear the sound from the phone when it's in my pocket, and with me always as I'm going in and out of doors, up ladders, etc. What I got for $16 was perfect for audio books, and a lot more! Now I get incoming calls, SMS and all the notifications from my phone, without having to constantly check my phone! And with sound playing from the SD card, it doesn't stop when I'm out of BT range, nor get static or run out of battery life fast, issues I was having with my BT headphones.
Still testing but the battery seems to be good for all day use. I'll post some more data after longer use.
Two card slots, left MicroSD, right AT&T cellular SIM card, when you have the SIM card in you have the option of making calls via BT link or Local, which means use the SIM card, same for SMS.
Micro SIM fits perfect, but Nano SIM worked too, really you'd want to use an adapter for Nano SIM.


The watch can display 3 different analog clocks.
