I haven't used it yet, but the appearance is good and the specifications I ordered are 800ml, but it's not too big or small, so I think it's really good to put in ice and eat a cool drink for a day.

Super! The color is rather dark gray with a little brown. Not as brown as in the article description. But I like it.

Super quality. I thought the chrome plastic ring was going to be of worse quality but everything perfect!
