I just installed this on my 2007 Chevy Tahoe after a few too long warm up winters. A few days later I like it. Installation was easy (I went with the snap-on stick that came with it, but a drill/screw-on option is also included). I let the pictures dry for a few days according to the instructions and then glue them on. It used to take up to 15 minutes to heat the air, but now probably 5 minutes? I could also run it automatically for a full 10-meter cycle, and the truck barely got hot in the MN…
