I had bought it for my own use and I am very satisfied compared to other water glasses. It does not leak when closed and now I got it as a gift for someone close to me.

It keeps the water cold for many hours, and it also doesn’t slip when you place it on a surface because the base underneath is silicone!

It is one of the best thermoses I have tried with very high-quality materials. Only a sensitivity with the straw—if it falls from not a great height while open, it breaks easily. However, the company has very good and prompt service.

It rusted near the handle after just a few uses! The spout doesn't suck well from the start. I do not recommend it under any circumstances.
Very poor quality for this price.

Excellent product! I got it for water and it was very convenient for me. All summer it kept the water cold for hours. It doesn't leak, it's easy to use and has a large capacity. I use it both inside and outside the house. I would buy it again without a second thought!

excellent product, keeps the temperature for several hours.
the only negative is that because it has a smaller base and falls relatively easily, the aid for opening the pacifier broke after a fall in 2 weeks (there is no replacement), making it difficult to open.

It keeps the temperature both for cold and hot. I am fully satisfied... I would buy again from the company because the package arrived protected and well cared for, accompanied by good maintenance instructions!

Indeed, it does not leak, but you need to use force on the straw to drink compared to other cups, so you feel like you are making an effort, it is not pleasant, it sounds and feels like you are drinking from a straw with a hole. Given the price, I don't think it's worth it if you have to think about it every time you want to drink water.
Update: It does not maintain the temperature satisfactorily. Note that I do not use ice cubes and the contents warm up very quickly. I suppose this is due to the transparency and the composition of the lid.

It is beautiful and looks high quality. Time will tell. The company is impeccable; they resolved an issue that arose immediately.
