A good, bordering on great smart watch, the only thing holding it back is the third party software on an iOS device. The watch itself is steel with a 2" face that is bright and easy to read. It comes with 2 bands, a silicone band with a buckle and a metal bracelet style band (which I prefer). The watch has a battery that lasts for over a week on a charge, but it doesn't charge wirelessly. It connects to your phone via Bluetooth, and when connected, the health tracking shares the data to your health app including your steps and heart rate, but the third party software doesn't work well with the latest iOS, hopefully there is an update coming. you have to use the included magnetic cable plugged into a USB power adaptor that isn't included. Through the Bluetooth connection you can answer/make calls and receive text messages, but since you are within Bluetooth range, it's easier to just use the phone. It has over 100 Sport Modes so it can track across sever types of activity. It is listed as IP68 waterproof, so it can handle sweat. It has several built in watch faces, and through the app, you can download and add a watch face that works best for you, and you can find the right face so it will work when doing activities and dressier faces so you can change it to meet your needs. The software is it's weakness. It may work better with Android, but the iOS just needs updating. It is a great watch that with the right/updated software, will be excellent!
