Good but leaks sometimes,
Verified Purchase(What is this?)
This review is from: Bobble Replacement Filter MU2 Band, Blue (Sports)
The filters for the bobble bottle do what they're supposed to. The water tastes significantly different than if you had just drank it from the tap. However, depending on the filter, sometimes you can get one that leaks a bit - not drastically and usually when lying on it's side.
Generally good product overall though if you hate tap water.
