My husband's is made by another manufacturer, and it's a hassle because you have to take the gasket apart to wash it, but this product has fewer parts and the mouth is wide, so it's easy to wash. It also keeps things cold well, so if you put in about seven ice cubes in the morning, you can drink ice-cold tea until the evening. As a little trick, if you pre-chill the tea by putting in ice and water, then replacing the ice and water with the tea, the ice will still be there until the evening. I like it because it's a light blue color and it looks summery. One thing to be careful of is that it has a wide mouth and no stopper, so if you tilt it too hard, the ice and drink will come out in a rush. Well, it's probably good that it prevents you from chugging down cold drinks in one go.
