The worst thing I have ever bought from Tefal so far. The lid is terrible, it doesn't close properly, it never opens when I have hot coffee inside so I can drink without having to completely remove the lid because the rubber doesn't fit properly! The hot coffee freezes very quickly. I have also bought the large thermos for hot drinks from them and it is the best thing I have ever used in a thermos. I have never made a bad review for a product before, but this one is very annoying!! Stay away

Not ergonomic at all since the lid doesn't screw on. It's not particularly thermally insulated either... I do not recommend it under any circumstances...

- The lid is not screw-on, you just push it down. It doesn't seal tightly, it's not suitable for a bag (it will definitely spill) and it's uncomfortable even for a car, as it can still spill during sudden movements or tilting.
In hot weather, it only keeps the drink hot for half an hour (maybe even less), then you're just drinking lukewarm coffee...
+ Beautiful design, it definitely makes an impression

It is a simple thermos cup.
It keeps the coffee hot or cold for a decent amount of time. You must always keep the cup in an upright position. It has a simple lid with a rubber seal around it that tightens but it is not waterproof, so it is not suitable for carrying in a bag.
It is not worth its money.

Completely useless unfortunately. I had to wait for the coffee to cool down enough because the steam created pressure (small), which caused the lid to come off. Even when I waited and it had cooled down, the result was the same. Within an hour, all the contents leaked out.
