The taste is really very great, which makes the filter from the tap water. A positive side effect: I drink a lot more during the day. Even coffee and tea taste just much better. The only drawback: The lid sometimes simply falls off completely, so that the half content spread everywhere. Did they just can pour without problems, so it can happen spontaneously during the next casting. We are thus obliged to use both hands when pouring because it secures the lid with one. This is a bit unfortunate, but to cope.
