Exceptional quality — perfect size and keeps food hot for hours
I previously owned the smaller Thermos Stainless King and it worked great, so I upgraded to the 24oz version — and this one is exceptional. I carry my office lunch in it every day, and the size is perfect for full meals. It keeps food warm or cold for several hours exactly as needed. The build quality is excellent, solid, and durable, yet the jar is surprisingly lightweight and easy to carry. It’s completely leak‑proof, so I can pack soups or curries without worrying about spills. The wide mouth makes it easy to fill and clean, and the Midnight Blue color looks absolutely terrific. Overall, a reliable, high‑performance food jar that does everything it promises. Highly recommended.

10 hours and still hot. The best food thermos I got so far.
Definitely a 5 star on this. I put my hubby's lunch together and heated up left over soup I made. This was at 1:00 pm he had time to eat at 8:00 pm and it still was screaming hot. If I could give more stars I would. I suggest to use a canning funnel to fill it, it fits perfectly and lots of room for the food you put in. The silver metal exterior and interior are nice. It's not heavy at all. The interior lid is plastic and easy to clean with no spillage. Everything was nice and hot and no metal taste from inside, just the soup.

Love it so far!
I really like this Thermos! I use it for my food and it keeps it hot for hours, which is exactly what I needed. The size is perfect, not too big or too small, and it feels strong and good quality. I I bought this Thermos a few months ago and I’m just now starting to use it, and I really like it!

Excellent all purpose small Thermos.
Excellent Thermal retention and convenient, we love it so much my family got a second one. We have packed everything into it (Mac and Cheese, Fried Rice, Pasta, and yes soup). When we travel with our kids, we rather pack homemade healthy food when visiting zoos and other attractions, not to mention cheaper than purchasing local attraction food. Self Containing with the spoon, it does hold it all nicely. Don't let the small container fool you, it can hold enough for 2-2.5 people. (we are not "big" folks, but not thin people by any means) We usually pack it in the morning and stays piping hot. Our kids have complained it was too hot when we open them during lunch and I can say it will keep your food hot/warm for about 6-10 hours as long as you don't unseal it. We have never tested beyond that range from our usage so take that for what it is. The two we own can hold more than enough food for our family of 4 during a lunch outing. We have used this both in cold and temperate weather with very little variation on temp loss. Finally while a little bulky, they are very light weight when empty and I didn't mind throwing them into a backpack when finished. Wide mouth makes it easy to load and clean when done.

Keeps Coffee Hot, Soul Warmer—Until the Insulation Quits on You Like a Burned-Out Intern
Let’s get this out of the way: when this thermos works, it really works. We’re talking lava-level coffee at noon, even if you filled it at 7 a.m. It’s like having a portable fireplace for your caffeine addiction. Cold drinks? Also excellent—think “ice cubes still clinking at sunset” vibes. But like any relationship, things can start off hot and eventually just… fizzle. What It Does Right: • Heat retention: It’ll keep your drink hot for hours. Not just kind of warm, but “burn your tongue at 3 p.m.” hot. • Cold retention: Ice doesn’t melt. Your iced tea stays arctic long enough to survive a road trip and a traffic jam. • Spill-proof: The lid is Fort Knox. Throw it in your bag, sideways, upside down—your belongings will live to tell the tale. • Sturdy: Built like a thermonuclear bunker. Drop it? It dents the floor. The Quirks: • Heavy: It’s not a thermos. It’s a commitment. You’re carrying a small steel cannonball everywhere. • Fussy lid: If you don’t screw it on just right, you’re risking a minor flood. It’s either totally secure or “hope you didn’t like that shirt.” • Cleaning: The lid has crevices that look like they were engineered by NASA. You’ll need a toothbrush, a Q-tip, and possibly emotional support. • Aging issues: After a year or two, the vacuum seal sometimes just… gives up. One day it’s a thermos. The next day it’s just a fancy, expensive cup. No warning. No closure. 💬 Final Thoughts: This is the thermos equivalent of that friend who shows up early, helps you move, and then disappears from your life after a year without a trace. While it’s working? Incredible. Practical. Dependable. But once the insulation dies, it becomes just an attractive paperweight with trust issues.

Classic & Durable
This is the gold standard for food jars. It keeps soup piping hot for hours, and the matte steel finish looks great. Leak-proof, safe material, and light.

A wonderful lunch thermos!
Excellent thermos! I love it! It's the perfect size to keep my lunch soups fresh, hot and tasty. The thermos looks nice right off with the nice clean stainless color. Assembly is so quick and easy, and it even includes a stainless folding spoon in the lid. I'm very happy with this purchase and will probably buy another trying a different size for other foods. Couldn't be happier with this thermos. It's a wonderful lunch thermos and I can highly recommend this one!

Cost effective, and great quality!
This jar is amazing! I have used it several times this winter when you just want something warm for lunch. In fact, I put the ingredients in, topped with boiling water at 6:00a and at 12:30p, my soup was ready- still too hot to eat. It's not terribly inconvenient to preheat with hot water before putting in left overs. It's easy to clean, the opening is wide. It works for cold things too
