The unit works well, the unit I got had problems reading the factory ECU, this was fine after it was swapped for a new handset. I wish it could read the car and determine the car and engine type on its own, the same as Bluefin, instead of the user needing to know the specific engine number of their car.
Also, the handset had some glitches, like the "next" arrow button sometimes being totally unresponsive and the user being able to turn the brightness down to literally zero, so that the screen becomes unreadable, and required a very bright torch to be held to the screen to see the LCD to fix the brightness. Hopefully these can be fixed in future versions.
