the only complaints that i ever had about that alarm was that there is no way to protect the buttons from being accidently pressed, and with the range it offers you never know if you are starting the car, popping the trunk, rolling the windows down, etc etc ...
that, and like said before, the battery life... but its a great alarm, i loved mine, and now my grandma loves it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
