Glass great effect, guaranteed effect when the glass is full. Be careful though to the width of these glasses that seems a little large and therefore impractical for one hand. Personally, I use it to serve a long coffee. The glass itself does not seem very bright empty .... but that's not the goal of course.
One star less because better not put in the dishwasher, a water bubble emerged after the 2nd washing, any record did not say it!
