I've used this carafe on a daily basis for six months, for hot and cold. It has worked admirably without any problems whatsoever, and I've gone through many carafes before this one so I know the problems one can have with breakage, leaking, not keeping things hot enough, and inefficient cleaning. I've dropped this carafe on a tile floor; it didn't break. I've run it through the dishwasher; nothing has leaked. It keeps ice solid for a full day in blasting hot weather, and coffee remains really hot no matter how cold it is. What I like best about this carafe is that it has a very wide neck. You can get your hand down there to give it a thorough cleaning. No more gunk at the bottom of the carafe! I like it so much that I am buying a second one.
