Customer Reviews

“I got this for myself in the pink and purple colorway. It is BIG! When I say big I mean big as in too big for just me!The size is not a negative in my mind. It is too big for me because I’m a smaller person but it would be just perfect for someone with a larger appetite.I won’t be using this for myself but we like to have picnics with my family and I already can see this working with a pasta or regular salad, or with a warm pesto, with fruit salad, and the list goes on and on. And the best part, there would be enough for everyone (I would think, up to 4 people) to have a bit and even more of a side each.The separate compartment is the weakest aspect of this lunch container only because it sits there kind of awkwardly. It doesn’t “lock” into place or fit tightly in there. It sits there loosely. But that is ok as that compartment is meant for a secondary item. And that is where the silicone lid makes so much sense. The fact it can close and provide a fairly tight vacuum (but not watertight) seal is a great feature.The main compartment’s lid also has a silicone gasket that locks into place on the edges and through a little knob at the top that goes through the middle of the plastic lid, and this ability to click into place makes it WATERPROOF! so go ahead, enjoy some soup on the go! And I have tested the container’s waterproof ability with just water and not a drop escaped.The spork in the lid could have had a way to be locked into place as it moves around in its dedicated space on top of the lid, but I’d rather it did than not having a spork at all, or it not having a dedicated space. It’s nice that it folds away.I haven’t tested its ability to keep things cold yet, but I wanted to see how well it would retain heat so I filled it 1/2 (20 oz) full with just boiled water and then I forgot about it. Literally. I went to bed and left the water sitting overnight. The next day, 19:30 hours later, the water had gone from 195 degrees to 92, so from close to boiling point to barely lukewarm. I’m sure it will do better than average with denser, piping hot contents from am to lunchtime. I’m calling this a definite win insulation wise.I’m so happy I got this. It will be on heavy rotation throughout the spring and summer. Worth the price.”

“I’ve tried a handful of food thermoses over the years, and this Pawtong one is easily one of the most practical for everyday use, especially if you actually want to bring a real meal, not just a small portion of soup.I ordered this thermo to bring home-cooked meals to my husband, who is in the hospital and is going to be there for a few more weeks. Hospital food stinks, so I’m cooking up his favorite stuff and it needs to stay hot ALL DAY, as there isn’t a way for us to heat it back up. And it works. If you preheat it with hot water first, it keeps food hot for hours. I can’t speak to the cold stuff because I’ve only brought hot foods, but it’s so insulated I’m sure it would work well.The capacity is legit roomy. I can pack a full lunch (think soup + rice, pasta, or even a hearty salad) and not feel like I’m rationing. The removable inner bowl is a nice touch too—it makes it easy to separate components so things don’t get soggy or mixed until you’re ready to eat.The wide mouth design is super important. It’s easy to fill, eat from, and actually clean (no awkward scrubbing). The included folding spoon is convenient in a pinch, and the hidden handle makes it easy to carry without adding bulk.Other things I appreciate:Leakproof seal — no spills in my bag so farNon-slip base — small detail, but it keeps it from sliding aroundSolid build quality — feels durable and not flimsyIf I had one small complaint, it’s that when it’s completely full, it can feel a bit heavy to carry around—but that’s kind of expected given the size and stainless steel construction.Overall, this is a great option if you want a reliable, larger-capacity food thermos that can handle real meals. For our needs it’s been a lifesaver.”

It’s big on the inside. I use it to carry my not oat oatmeal to work for breakfast. Keeps my food hot! Easy to clean. The metal spork is very handy. I love the carrying bag it comes with and I use every time I take it work. No leaks. I love the seal release on the top, I’ve had to use it a few times to open the container. It works perfectly! Easy to clean. This was such a nice food container, I am looking forward to buying more!

I’ve used mine about 3 times now and I am happy with the ease of use and functionality. It is very convenient. I wanted warm meals to bring to work but using the microwaves seem to make my food more inflammatory 🤔 I heat my food up on the stove as I get ready for work and now I don’t have to use the microwaves at lunch time. It saves me time during my lunch break. The size is perfect too (I got the 24oz). No leaking issues so far. The food is kept warm but does cool off a bit by the time noon rolls around. It keeps enough heat for me to feel satisfied with the product though. I don’t let my food get boiling hot before I put it into this container anyway. Great product, highly recommend!
