It keeps beverages and water cold for several hours. However, it is not a quality product at all, as within a month of use, the lid started leaking, resulting in the contents spilling. The warranty does not cover it. Legami's warranty only covers purchases made through the legami.com website. It is not worth the money.

It was fine. However, after two years of purchase, it rusted on the inside, so I couldn't use it anymore.

I am very satisfied overall, the only problem I encountered is that after a period of time, the rubber band inside the lid wears out and falls into pieces inside the water. That was bad, and the company does not sell individual lids, so I will not choose it again. Other than that, it's fine!
