With SO MANY alarm / remote start brands in the market to choose from (i've owned or installed almost every one of them) Firstech is by FAR the best ! Not only is their product practically ""bulletproof"" and has never failed me, they always have the newest cutting edge technology & features. I'm on my 5th vehicle in a row using Firstech Alarm remote starts and 3rd in a row adding their Drone Mobile (cell phone interface) module for ultimate control, GPS tracking & peace of mind. I'll NEVER change brands. Thank you Firstech for putting out such great products.
