I have a couple of these watches. They're basic, but capable.
What is the battery life? I have a Huawei watch GT2 (it cost £60), and the privacy concerns do worry me - I try not to connect it to the Internet - but for a watch that supports timers, stopwatches, alarms, phone calls, sleep tracking, HR tracking, SP02 tracking, compass, local and Bluetooth music playback, always on display, and step tracking, the 14 day (without always on display) and 4 day (with always on display) battery life just makes it impossible to get anything else, especially those 'smarter' £200 watches that barely last a day. I also like the round display, makes it look more like an actual watch, and not a little computer on my wrist.
