Review: I only had this watch briefly, but it is great to see a company pushing the technology and software that once only seemed available in watches 4-5 x the price. This watch is a great substitute to the Apple, Samsung and Garmin brands of the world, basically giving you the exact same tech and abilities, for a fraction of the cost. However, don't expect all the bells and whistles of perfect phone integration, compatibility with thousands of apps nor the ability to phone home with this brand. These are the concessions you make by paying far less, for an equally capable, rugged, well polished watch, without a thousand dollar bright shiny name on it. It will still jump out of a plane skimming the stratosphere with you, while plunging into the deepest depths of the ocean with you, and tell you the time and possibly your heart rate while doing so. It just won't make you feel guilty for overpaying for the privilege of having a great watch on while doing so. It runs apps beautifully, and gives you a nudge on the arm every time someone uploads a family portrait or lunchtime selfie, and will let you know when your boss is calling to find out where you are. It just won't say that the call is brought to you courtesy of Apple, or Samsung, or Garmin. And that's probably worth saving a few $$$s for. Highly capable, highly recommended watch.
Review: I can't say enough good things about this watch. It has nearly everything that I could ask for from a smart watch. Super durable, water proof, dust proof, long lasting battery, always on display, tons of watch faces to chose from, compass, barometer, calendar, multiple ways to reply to messages, alarms, timers, monitored sleep and vitals etc. The only thing that would make it better is if you could create messages to send or take phone calls from the watch but besides that this is the perfect watch for me. I work with concrete and I also do metal grinding and welding and this watch holds up amazing. Highly highly recommend.
