THERMOS Stainless King Vacuum-Insulated Food Jar, 24 Ounce, Midnight Blue

Hoping to save money and eat healthier, but wanting a hot meal, I was looking for something like this.PROS -- PORTION: The portion size is great, almost too much sometimes. KEEPS FOOD HOT: I'll prep it by adding hot water to the canister and letting it sit while I heat up soup, spaghetti, etc. At lunch time, my soup is often so hot its almost too hot to eat. If you don't pre-heat, it cools off a little but still plenty warm. I haven't tried going more than 5-6 hours, but easily keeps food warm that long. LEAK PROOF: 100% leak proof, and this was one of my biggest concerns. So far, not a drop as leaked. It has 2 lids, an inner and outer, to seal it up. The outer can also serve as a bowl.CONS -- the lid is a little small to actually use as a bowl, so I just eat right out of the container. And that's the biggest con: the opening is a little more narrow, and the container a little deeper than I'd like, but it works. If I had to redesign at all, I'd maybe make it a little shorter and the opening a little wider - but overall, its doing a great job for me. Still easy enough to clean.At the price of eating out, I figured 3 fast food meals was my break even point, and I'm saving money with every meal I pack going forward. And eating better food! I wish I could give 4.5 stars.

After buying so many products that fail to live up to reviews and ads, I have decided to start posting my experience with every new purchase with tests and pictures so others can make up their own mind. I have already stopped buying USB cables, wire, etc that are not namebrand or certified as in the case of HDMI cables, etc. Yeah.... real products that work costs a lot more but as a tech business that installs sound, lighting, and video systems, they have to work. I don't have time to fiddle with crap parts. Been there, done that, and I'm through. The same with stuff I buy for the household. From now on, things that don't match the advertised expectations I'll return immediately.Last night I put water in this thermos at 164 degrees around 11 PM. Today I checked around 11:30 - about 12 hours later and it was 140 degrees. Excellent! Obviously I would likely not wait 12 hours to eat whatever I put in there for lunch, likely I'd load it around 7AM to eat around 12 or so, this thermos should work fine for that length of time. This is a keeper. It's smaller than what I thought it might be, didnt look at the details close enough, but the portion size is adequate for a light lunch. I would consider getting another one for another food item if wanted sometiung like stewed beef in one and rice in the other or consider one of the larger products I saw that is powered by 12v / 120v. But my needs are ocassional as I dont spend that much time on the road. This will work fine for my needs.

In a perfect world, this would be a wide-mouth jar and therefore convenient to directly ladle in chunky homemade soup, but I adjusted and used a canning funnel and all is well. I filled one with super hot, (unable to eat) chunky veg soup at 6am, and by lunch at 10am, it was perfect temp, albeit a little too hot still to consume quickly. You need to keep the top on it to avoid any potential heat loss through the single wall neck. The second jar I filled with room temp mango juice and four big ice-cubes. I expected the cubes to melt down quite a bit while cooling down the juice and then hit a cold parity, and checked it at 7am. Since 7am the cubes have barely shrunk in size over the last 3 hours. Again, keep on the lid, and not just the stopper by itself. Simple physics. I will source replacement seals now for future use. The food savings alone will more than pay for this jar in the event I need to buy another.

Keeps food hot all day!

Works perfectly. Been great and keeps food warm long. Been using for about 4 to 5 months now and is still very durable and works great with no issues. Pretty easy to clean depending on what I put in it. Sometimes I have to use a brush. My hand definitely doesn’t fit in it or to the bottom. Great size to feed a teenage boy his school lunch. It seals tight and have never had an issue with anything leaking.
