it leaks...nice idea.but always got water all over myself,no matter how i screw it on...sucks
I love this bottle. I had a Brita filter bottle about 5 years ago and was really sad when they stopped making filters for it. It's easy and convenient to have filtered water anywhere. Just take the empty bottle with you fill it up at any tap. No need to lug around bottles full of water. I bought 4 extras filter so I wouldn't run out.
