I really like this filtered bottle much better than the regular Brita filtered water bottle. I like the cap that swings open at a touch, and I did not expect to like that as it is a step between me and my water. The water tastes good and is easy to draw through the straw. I rinsed the filter well and did not have any of the issues others have had with loose charcoal particles. The one thing that I do not like is that the lid, when closed, doesn't seal the mouthpiece well enough to prevent a stream of water pouring from the bottom of the straw when I take the top off to refill it. Instead the water pours from the straw after a few seconds delay, which is frustrating when trying to refill at a water fountain in public, with water pouring sometimes all over the floor surrounding if one forgets to drain the straw. The Camelbak Groove filtered bottle didn't do that because of the closed mouthpiece. I was hoping this Brita bottle with the lid would accomplish the same thing.
