Overall, this is a reliable food thermos for basic use. Personally, before I use it, I put boiling water inside for a while to preheat it. I need to open the valve because, due to the temperature, pressure builds up and makes unscrewing difficult.

It keeps the food lukewarm for about 1–2 hours, which is sufficient for my use. The important thing is that it closes well and there is no leakage at all. It was given to me as a gift for my baby and within this timeframe I have enough time to give them their meal properly.

However, if you are looking for a thermos that keeps food hot for many hours, then this is definitely not the right choice.

I would give 5 stars but the clip on top breaks very easily. Other than that, though, they are very good and durable.

Safety lock. Nothing spills. Of course, it doesn't keep it hot until my daughter's all-day school, just warm to lukewarm I would say

The food stays warm for only an hour. After that, it gets completely cold.
The lid shouldn't be tightened too much because it sticks and won't open at all..

I bought 2 together so the kids could take them to all-day school, but many times, even though it seems to close properly, it opens (the lid pops off), resulting in all the food spilling into the bag. On one of the two, from the beginning, sometimes the lid wouldn't snap on, it kept turning as if the threads were broken. Unfortunately, I will have to buy others, it's a shame for the money

I bought it in September for school, on the first day the handle broke, in November the small valve came off and got lost. Useless now and there is no spare part, although I wasn't particularly satisfied with how long it kept things warm either.

The good thing is that it doesn't smell like another thermos I had bought

I bought it for my little one's all-day school. Unfortunately, it doesn't keep the food warm even for 5 hours. The plastic handle broke immediately without much pressure. On the negative side, if the child loses the valve, the bowl becomes completely useless. On the positive side, it is very easy to clean, does not retain odors, and closes very well without any leaks.

Very good purchase! I bought it both for the children's food at school and for us for work!
