I just used mine this morning and only had it on for about a minute, not more than 2. It does get very warm very fast. I just use it so the steering wheel isn't ice cold. It's currently 33 degrees for me. Speaking of smells, has anyone else noticed that it almost smells like burning solder when the heat is cranked? That's gotten me slightly worried a few times, no smoke or anything, but smells like hot metal/burning solder. I have gotten my hands pretty warm on the steering wheel, but never burned them because I always turn it off.
