This is the single best purchase I have ever made on Amazon. And I buy A LOT of great things on Amazon!
My work is gross. Like really gross. I work for a trash company gross. We have a roach problem in the kitchen gross.
I simply bring this puppy in with my leftovers inside (any flat bottomed container works but I use the 3 cup pyrex ones everyday) and plug it in. I bring one dish for lunch and something foil wrapped for breakfast. i.e. burrito. I slap the burrito in and eat that in 2 hours when I start to get hungry after my coffee, toss the tin foil away and slap my leftovers in it, eat that in about 2-3 hours (as this never overheats my food) and then just unplug it and eat! I take the whole thing home when I'm done so no bugs get in it too.
Pros: I can keep my food out of the actual kitchen that is disgusting, it's on my desk that I clean religiously every day. It's hot when I want it and doesn't get that microwaved effect and it's completely and evenly warm! (Sooo happy I don't have to use our microwave that is also rusty on the inside, who knows what that does?!)
Cons: None so far - this thing works like a charm!
Definitely get this if you drive a long time or work somewhere without easy access to a kitchen...or in my case a CLEAN kitchen!
