I installed this in my friends Escort in June. No problems so far and the install wasn't bad. I wouldn't put it over a more well known system out there, but he bought it and asked me to put it in for him.
it is a PIECE OF sh*t. it sensor is crappy. i only had it for a week for sh*ts and giggles. but i guess its better than nothing. i only like it because it would say, system armed and system disarmed with a robocop voice
