I've had remote starts on every vehicle since the 90s, except a manual Ranger....and I only used RS about 12 times per year, if that...and I've lived in MA and now in TX, so places it is useful.
If you've got a garage that cuts use in half. And half the time when it's hot I forget to hit the button until I'm basically in the truck. I get everything ceramic tinted, so that helps. Plus, today's vehicles cool and heat pretty quickly.
The Ravelco really, to me, is for parking in unknown areas. I park right in front of my office, for example, so no real need there. I don't park at airports, so stealing it there won't happen.
So, long dinners, movies, stuff like that is what I'm getting this installed for.
