One of the best cheap smart watch in the market Some Disadvantages It has purpose. The screen is small and quality is missing a lot. Responding to your touch has-been updated with the last update. Purpose maybe you will face a problem with the update it self. You will find a lot of apps supporting this watch so I think you will not get tired of it very fast. It's only no sound vibration. Light on your hand purpose watch out the water. And of course do not do heavy work with it. Price is fear. We Hope that Sony can Improve it and present something better.
