100% no spill! Even if you use it as a shaker, not a single drop spills. It has a nice grip that doesn't slip from your hand. The downside is cleaning: you have to be careful not to leave any residue inside the cap in its mechanism because it will start to smell, especially if you use milk. I don't have a dishwasher to tell you if it gets cleaned there.

Yes, it is of very good quality, yes it keeps the coffee hot for many hours. I would say it is hot.
Yes, although the lid system is very complicated, it is well-made and shows that it will not break.

I consider the button you press to drink a negative aspect.
The price is also a negative aspect.
Lastly, there will always be a little coffee left in the mouthpiece, which is necessary if you forget and don't sip it like eating snails, to get dirty.

Not from me at this price

I bought the thermos for work. It keeps its contents, whether cold or hot, at very good levels. In my case, the coffee stays hot for 8-10 hours if you don't open the lid, and 6-8 hours if you do open the lid. It has a safety feature on the mouth to prevent leakage. The lid locks to prevent the mouth from accidentally opening and spilling the contents. I am still very satisfied. The color on the thermos may fade at some point, but that doesn't bother me.

I have had it for over a month and I am very satisfied. It has very good insulation, meaning it keeps hot drinks warm for a long time. It doesn't leak from anywhere and the lid with the safety button is very practical. Quality construction, fits in the special compartment in the car and also fits a straw for frappé through the opening in the summer. The purchase was worth it.

It is very well made, and the fact that you press to drink is very clever, zero leaks BUT. In the hand, it is not that easy to clean and the lid and the rubber on the mouthpiece retain odors even if it has been put in the dishwasher. So, you can't put a strong aromatic tea and then want to drink coffee the next day, you will be drinking something very strange.

Excellent, it does not leak in any case and keeps the coffee hot even after an hour.

Edit:
After two years of daily use, I have to say that it is the best purchase I have made for a thermos. It still keeps my coffee cold or hot for many hours. During the winter freezes, I cover the lid with aluminum foil to minimize heat loss. To my surprise, the mechanism in the lid has not broken and it works perfectly. Lately, I have also been using it in the sterilization device to heat up water for my baby's milk when I go out, and it doesn't seem to have suffered any damage. The only thing that has happened is that the color has peeled off gradually, changing from fuchsia to silver, because my 2-year-old has dropped it multiple times (but it didn't break). However, it has also been scratched because I put it in the dishwasher every night, causing the scratches on the exterior color to become more visible until the color completely disappeared. But it doesn't bother me much. When the thermos breaks, I will buy the same one again.
