Easy to use, reliable, slower than anticipated. Very easy to install on the computer and the Android, ignore the warnings on the PC application that it will only work with certain devices. Although I have a very fast Wi-Fi connection, it seems to take about a half a second per megabyte to transfer. That means if you are transferring large video files, be prepared to take a nap. Other than that, great application. I would trust Asus, one of the world's largest manufacturers of PC's and motherboards, to not be making copies of my files as I transfer. wow lol
