Viper's elegant new Responder LE transceivers mark a giant leap forward in 21st century remote start, and an evolutionary milestone for the keychain remote. These slender & sophisticated 2-Way remote controls feature a clean sleek ergonomic industrial design, made to fit the user's hand comfortably, enabling effortless and intuitive single-handed operation as Brilliant LEDs confirm your commands.
I have been enjoying this remote start with the comfort of starting the car from far. Only thing that I feel it could have been better is it would work beyond walls. Sometimes even when I m within half a mile, it does not work if there are walls in between.
