Nice device, could replace your smartwatch
Advantages: The smartwatch is as described. It has Android 5.1. I could install apps from Google Play. The following apps ware tested: WhatsApp, Maps, Mail, Tasker, Business Calendar 2, Business Tasks. The voice calls can be done easily and the voice can be heard very well. If the sound is too laud for a room with people, you can lower the volume to the minimum and put it close to your ear. The microphone is sensitive enough. The wrist band has a silicon feeling and seems very soft and smooth. I could install Tasker and with it I got access to some hidden settings (which are normal for a smartphone) , but hidden on here. Typing is difficult, but as you practice it gets easier.
Limitations: The battery level get down very fast if you have Data enabled and use the phone. If you disable data and wifi and don't play with it too much the battery last for a day at least (you can see in the picture the behavior of the battery after ~10 hours). The charging is done using the adapter and if you do not have it with you, you can not charge the watch. I could not find separate adapters to buy. Android 5.1 does not allow you to control from other apps the data service, which means you can not automate this process without root and rooting it is challenging, at least at the time when I am writing this.
