This is the best pitcher I have ever owned, and I can't think of a thing for it to improve on. It feels sturdy and durable, you can't beat how fast it filters, and the water tastes fresh and clean. It's compact but hold just as much water (if not more?) than a Brita. I also like the way it pours -- the handle feels nice in your hand, the lid stays on securely and the flap for refilling stays closed (it's magnetic).
Filling up a Brita pitcher is always top-heavy because it has to slowly filter everything from a reservoir at the top. That means you can't use the pitcher until a few minutes after you've filled it, and once the water filters through, there's about a third of this pitcher that's just empty, bulky, wasted space in your fridge.
