Very good, with a rubber bottom underneath so it doesn't scratch surfaces, and the main thing is that it tells you exactly how much temperature it holds and for how long with diagrams. No other manufacturer does this, I had bought 5 different ones from various others and none of them hold as much, nor do they say how long they hold.

It is the 4th water bottle we have purchased because our child broke all the previous ones within a 2-year period, which turned out to be very fragile!! This water bottle appears sturdy, opens up completely, and is easy to clean. It keeps the temperature for many hours. Finally, I want to point out that it has a rubber base that makes it more stable. If I had made this purchase earlier, I would have saved 80€.

Excellent temperature retention. Even without the cap, it keeps ice in the coffee for a good 2 hours. Time will tell about the durability of the outer coating, however, the 2-stage cap (only the small spout can be removed or the whole thing to turn it into a cup) is very convenient
