Awesome feature with the smart phone but this much money on the alarm then additional for a year to use the service. I dont care much for the gps tracking unless my car gets stolen or towed. I had a kill switch added since this does not come with one but you cant even use the smart phone feature unless you pay. I dont mind paying just wish i knew a head of time and i rather someone get a regular 2 way remote because after instalation and alarm you are already a lot of dollars in.
