The most important feature I like about this product was its ability to work in any platform or device that supports TCP/IP protocol such as Android, iOS etc. It also has an option called 'Open API' which helps us access it from our other devices too without worrying much. There are some bugs at times so sometimes you feel confused but soon everything will be back to normal with new updates. This should definitely have been available free rather than paid version if they want more users. If your looking out something cheap then go ahead otherwise pay extra money because these features aren't worth paying even though there's nothing wrong using them just make sure not to use while traveling where phone battery life may get drained quickly. Easy accessibility anywhere anytime.
