I have had no problems with this alarm/remote start since I installed it in my car. It does what its supposed to and has cool features such as a display of the tempature inside the vehicle so you know if its warm enough yet on those cold days and also shows you the battery voltage. I would reccomend it to others to buy. Less expensive then some of the big name brands and does just as well. LCD remote is pretty cool and after a little readingof the instructions pretty easey to navigate the menus and change settings. Only bad thing I have to say is that the crank time on the remote start is just short of starting my car, on the second try it fires right up,(older car, high compression motor) you can set it to crank longer through the remote but I dont want to over crank the starter. All in all it was a good purchase.
