Design: Deberia venir para uso plug and play, no viene con manual de usuario. Se debe instalar una aplicacion para su operacion, la cual no se encuentra en play strore, solo el fabricante la puede entregar. No es facil la carga del equipo sin el uso de la aplicacion. It should come as plug-and-play, but it doesn't include a user manual. An application must be installed for its operation, which is not available on the Play Store and can only be provided by the manufacturer. Charging the equipment without the application is not easy.
