I have it, and its great. I love the 10 model memory so I can use it with all my trucks. the telemetry, like MotoGod said really isnt useful besides the voltage meter. Thats all I use. The temp meter is a good 15-20 degrees off from my temp gun, and the speed meter broke on mine within a few weeks. And while ur driving, and racing you dont ever look at the screen. Down the road, i want to pick up a Futaba 4PKS for the different functions, but for now the DX3S is definitely a great radio!
