What I dislike is it is a little difficult to remove when I wash the bottle. I might have screwed it in a little too tight, but wanted to make sure it would not come out.Overall, I love the filter because it does a great job filtering my water and I can definitely taste the difference. Love these filters.I will try screwing it in a little less tight!!
