Internet Smartwatches Newest T8 BT3.0 Smart Watch Support SIM and TFcard Camera For Android For iPhone Sport Smart Watch Phone Wrist Watch (Black, Case size: 45 * 53 * 12mm)

I was a bit dubious about the battery life, but my T8 has been running for 25 hours + and it's still going. The phone call/receive response is equal to my Samsung Galaxy. Forget about the camera - it's just a gimmick, but the rest of the watch is pretty good

Unbelievable value and style.
