I LOVE LOVE LOVE LOVE LOVE this thing!

Leak-proof and holds 12-14 oz. I have been trying to find something sleek that holds enough that you don't get thirsty because whatever you're drinking finishes too soon.

I like that the outside does not condense and stays room temperature while the inside stuff stays super cold/hot.

I LOVE the drink spout and the fact you can open/close this with one hand.

Very sexy and comes in different colors. I want another and am waiting for a better sale.
