Like it very much! On the cover of the hole 2, which is very convenient, air escapes through the small drinking. Whips also good. Inside the cover rubber ring (circle) .Kokteyli also liked (made with milk), especially Blueberries & Cream (with real blueberries) and Double Fudge Crunch (with crispy crumb pastry), perfectly melted, leaving no lumps or unpleasant "powder" taste, wonderful satisfy hunger, I think you can easily replace them one meal!
