I have the taller, larger concave/hourglass shaped one and LOVE it. I decided to try the smaller one. The first one got water and condensation inside when it went through the dishwasher. They replaced it with this (I never checked the nicely packed box before taking it - just assumed it was the same) and it's smaller and the rim curves inward which along with the double wall had me dribbling tea out my lip! :-( I'd like to exchange it if possible next time I am in Canandaigua.
