Water filtered with Zerowater tastes so clean and crisp.  Even though the filters are more expensive than other brands out there, it really does a better job.  I have another brand filter and the same tap water goes in both, but the water that comes out of the Zerowater filter tastes noticeably better.
I like the new design of the pitcher so that even if I've just refilled the reservoir and there's unfiltered water up top, I can still pour a glass without the top coming off and water spilling everywhere (that was a big flaw in the older pitcher design).  My only complaint is that the spigot at the bottom lets too little water through so filling a cup that way takes too much time.
