I really love the feel of this tumbler, it has a nice weight to it This tumbler does have a vacuum seal to it, you can feel the air pushing out as you push the lid in. There is an air hole on top so that your drink will come out when you drink from the cup so its not completely leak proof. This tumbler will hold 20 oz of liquid and I can put in a fair amount of ice without sacrificing the amount of drink I have. This tumbler is so easy to clean because of how wide the mouth of the cup is unlike a water bottle. The clear lid allows you to see whats inside the cup which I find to be really cool. This cup is heavily insulated and it can keep your drink hot or cold, to me I like cold drinks since I wouldn't drink this large amount hot liquid ever in my life.
