Question: Hi all, does this really work? I mean, heating up food in a plastic container? how warm can it get?
Document: These heat up the best since the bottom is flat and allows the most contact with the heating element. Nothing dries out or burns as the lid prevents moisture from escaping.Plastic tupperware type containers will work OK. A loose tinfoil wrapper helps, but this still won't warm your lunch up as hot as the glass containers. Depending on what you're heating, it could still result in a trip to the microwave.Today I zipped a frozen lean quisine into the warmer - box and all.
I put the whole frozen box in here without even taking it out of the package when I get in to my office. By lunchtime, it is cooked perfectly... I mean PERFECTLY. Microwave frozen food really is terrible, but this thing cooks it slow and to the perfect temperature so that everything is tender and just PERFECT. All grocery stores need to have this unit in the frozen food section.
When I am ready to eat.. Ta da! Hot food!I've tried prepared frozen meals and to my surprise, the food was delish!I've used plastic containers and glass containers and I must say the glass container is the best! The glass container is a bit heavy carrying to work every day but well worth it.The only suggestion I have for the manufacturer is to add an on/off switch.
This oven will not pressurize the inside of your container. Microwaves are horrible about that because they heat the water very aggressively so that some of it is boiling even when your food is cold in the middle.I plug this thing in when I get to work at 8:30am and when I eat lunch sometime after 11:00am the food is perfect. I was concerned at first that this might overcook my food leaving it in there so long but it does not.
Bought this and the mini crockpot for my daughter to take to work. This unit works really well for both frozen meals and for warming up leftovers. Works with cardboard, plastic, foil and glass FLAT BOTTOM containers.
Now, for the HotLogic warmer, I can have my own meal warmed and held in a container compatible to my choice (Glass-Lock) to deliver to me an instantly gratifying hot lunch in my work environment to satisfy any stickler for individualistic superiority. All the other lunch-minions scurry for some mucked-up public microwave to scald and scorch and boil their miserable leftovers or plastic, industrial, MSG ridden, convenience poison, waiting in line for the scarce minutes to sit down to their reluctant pseudo-nutrition.
I have turned cheap cake with a dollop of cream cheese, frozen berries and white chocolate chips, into a tasty warm desert to round off my private dinner. There is no way I would wait to pay top-dollar for such excellent results. The thing is that I merely placed the ingredients in the container, sealed it up and packed it for the next day or two in the fridge. Then I plucked it to carry to work and placed it in the HotLogic first thing, forgetting it.
I wish it would get just a little hotter, but it's pretty decent. I use it for travel, so I can use it in a motel also to warm up leftovers or what have you, and it work pretty well for that but it takes at least an hour to warm stuff up so you have to plan ahead, which is okay for me.
Got this bag to travel and heat our meals on the road. It works really good. I got a Pyrex dish and put inside and it heats up the food and keeps it warm.
My husband ordered this and I was skeptical. I haven't used it myself, but I saw the results of the test run my husband did when it first came. He fixed a lunch in a multi- use plastic container, left in in the fridge over night and heated it up the next evening. He was very pleased with the temperature of the food and the fact that the container didn't melt.
Answer: I ordered my hotlogic for my office about a month ago & it's terrific!  I put frozen food (in either glass or plastic) in when I get to work, and it's hot by lunchtime - never too hot.  I've put a grilled sandwich from the night before wrapped in foil, perfect... cold home made soup in a plastic container - takes about an hour to heat up.  Never seems to overheat, no cold spots like a microwave.  I'm amazed actually!
