Convenient size and handy to reheat food. Would not purchase again. Unit must be closely monitored. Cord gets very hot within 3 minutes of operation. To heat food and NOT melt the cord you need to cycle on and off. I would call this dangerous. If you do purchase this oven, pull over and take a break while cooking. I was planning on plugging it in and heating food while driving so it would be ready when I stopped. This will quickly melt the power cord before your food is warm enough to eat.
--- Drivers, please be careful as you prepare meals in your trucks. The situation that this reviewer describes may be exactly what happened to the many Pot n Pop 12-volt hot pots that we used years ago, which kept burning out after a short period of time. ---
We wish you safe travels and lots of money saving opportunities on the road.
