Bought it for $20.00 off Craigslist. It works pretty good for what it is. I may take a bit of time adjusting your cooking times in reference to your driving times. What I mean is if you have a couple hours of drive left before you want to stop for dinner then you will want to plug it in for 30 minutes to get it up to 350 before placing your food in there to cook. On the other hand, if you’re just reheating your food and not necessarily “cooking” it then you’ll have no problem at all. I think it’s a great product along with a great idea. It will save you a lot of money from eating out at restaurants every day on the road.
