I've got mine in the car. I haven't had a chance to get it on the track yet but it seems to be fine. I did test the range on it though and I want to know where they get this 3000 foot range from. I had my wife watch the car in the garage on a stand and I went and walked down the street to see how far I could go. I got about 300 feet away and lost the signal. Granted, I'll never be 300 feet away from my car, I hope, but where's the truth in advertising?
