Query: does its job and fits in the refrigerator!

i have used Brita pitchers in the past, and this is an improvement in design. The water doesn't rise back up into the top, no charcoal flakes and it fits really well in my refrigerator door. i bought it to use with my new Keurig coffeemaker so it won't get too calcified with our water - so far, so good!
