Pack it the night before
900 ml of whatever you actually want to eat, sealed leak proof.
Press one button
The waterless system heats evenly on its own 7200 mAh battery. No socket, no queue.
Eat, then rinse
The stainless steel tray lifts out and goes straight in the dishwasher.
Lunch stops being the worst part of the day
Most of what makes cooking tiring is the setup and the clearing up, not the cooking. We pick the things that cut both.

This thing is perfect for my office setup. No more waiting for the microwave.
Finally, my food doesn't have those weird cold spots you get with a microwave. It stays moist too.
I took this on a long drive last weekend and it was a lifesaver. Being able to have a hot meal without stopping at a greasy fast food place was huge. The battery held up well for the whole trip. Highly impressed with how it performs away from a plug.
My WarmBox arrived yesterday and I am already using it. It is so convenient and looks sleek on my desk.
I stopped buying expensive takeout for lunch. Bringing leftovers and heating them in this has paid for itself in two weeks.
I was worried it would take forever to heat up but it is actually pretty fast. About 30 to 40 minutes and my food is steaming. It is very quiet so it doesn't bother anyone in the cubicles next to me. Love the stainless steel tray too.
