I have used it for about a year. Highly recommend it to all pilots. It works flawlessly on my Samsung Galaxy phone  Samsung Galaxy Tablet  and LG cell phone. I fly with the tablet for navigation and one of the cell phones to get information about airports and frequencies plus nearest airport as I fly each leg for any emergency should one occur. The second cell phone is for a backup should I loose operations of the other 2 devices. If you fly this is a must have for your safe flying.
