Question: Can i use this with plastic bowl?
Document: 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.
Let me start off by saying that I use this with a container that fits perfectly inside. The description for this container on amazon is: Pyrex Storage 6-Cup Rectangular Dish with Dark Blue Plastic Cover. It took me a while to figure out exactly what container to use so I want to save people some time. This container costs $6.55 on amazon at the time of my purchase.
I pop my lunch in when I arrive in the morning, and by lunch time it's almost too hot to eat. I love this thing. Somehow it hits that hot spot (no put intended) between cool enough that I can throw in a plastic bag of frozen soup, but hot enough to heat pretty much anything to a steamy, meal temperature relatively quickly.Only downside is that, not having to go use the disgusting, shared microwave, I miss out on some watercooler chatter.
This is something that I was really needing. I carry my lunch a lot and get tired of just sandwiches. Now I have Soup, Chili, Stew whatever. I use a Pyrex glass dish to heat in and it works great. Some ask does it get hot enough. The first time I tried it I burned my fingers trying to get the bowl out of the case. Dummy me. Yes this get HOT but it does not burn or scorch your food. Again a great item
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.
I bought this to warm up food (especially baby food) on the go - in the car. I have used it only 5-6 times, but this has worked out very well for us. Cold items take about 30 mins to become lukewarm (slightly higher than room temperature), which is good enough for my baby. This fits the 6-cup pyrex glass bowl with room to spare.
It was outstanding. You can leave your food in this thing for a long time and it will be fine. If you are a few hours late to lunch no big deal, it will still be better than microwaving. The secret is that it cooks your food in a sealed container with very good temperature control, trapping the moisture and odor inside. Since it cooks gently and from the bottom you do not need to worry about your plastic lid.
This is an awesome product. Warms food to about 180 degrees Fahrenheit. Hot enough to keep bacteria at bay, but cool enough to not melt Tupperware and plastic bags.Works great with my $15 140watt cig lighter inverter in my truck also (only draws 45 watts), and folds flat to store under my seat.Highly recommended
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.
I love this little slo cook oven. It's been a godsend for me as I have no kitchen. It cooks chicken and fish in 1 hour. I also place eggs in a small plastic cup and steam them in water for about 1 1/2 hour and voila, I have poached eggs and they are great. My only complaint is that it doesn't seem to cook vegetables. I've tried to cook them for over four hours and they were only half cooked.
Answer: I used the Rubbermaid "Take Alongs" which fit perfectly in the portable oven. It has a red lid. It holds 4 cups. That will give you an idea of portion size as well.
