Not airtight at all, the entire contents spill out, the lid on top does not fit at all, and there are faded spots on the logo.

It is reasonable that it would have some leakage due to the openings for a straw, but this one leaks uncontrollably when tilted. It is bulky so it does not fit in cup holders of European cars. It is meant to be kept steadily on a desk, not to be carried around with you.

Excellent as a material, keeps cold and hot exactly as advertised. Feels like an expensive product.

It is quite heavy to carry around all day, at least the 1200ml one that I got, but it is a sturdy construction

The second one I buy. Amazing quality, it keeps the water temperature with ice cubes for many hours.

Amazing thermos. It keeps the coffee cold until late in the afternoon even if the sun hits it all day.

Excellent if you add ice cubes, they are preserved until the next day. After buying various thermoses, this is by far the best, it is worth its money and is very high quality.

️ Strong, as far as maintaining the water temperature is concerned.
️ It does not have a cap to close it, when you don't want to use the straw or want to put it in a bag.

If I had known how much it would help me drink enough water, I would have bought it sooner.

As a perpetually dehydrated person, I was trying to find a way to drink more water. Reminders, apps, various pretty bottles—nothing helped enough. Filling and counting glasses? One time I spilled the glass on my Mac, and since then I have a phobia. I got the idea to try this super expensive—let’s be honest—and viral thermos, because in the summer I drink colder water, while in the winter I like it warm, and guys, it saved me! It’s also the right size, because the 1.18-liter one is huge. So I fill it 3 times a day, leave it on my desk—handle—straw and I empty the water without even realizing it, easily! If you have the same problem as me, I highly recommend it!

Durability over time will confirm or not the 5-star rating and the premium price. So far though, very good.

The best! Have it 3 years now!!!?️

It is not splashproof as stated. There are thermoses for much less money that are more splashproof. This one may be defective.
