We use the water filter from BWT for almost two years and are still convinced of its benefits. Although we have a very hard or hard water, this is decalcified noticeably what we positively noted especially for the devices such as kettle, etc. The duration of action is sufficient - it can be made about 80-100 fillings of table water filter before the effect wears off appreciably. A change in taste or a difference to our unfiltered tap water, whether in the positive or negative sense, we could never find. This set offered here, including the water glass is worth the money in any case and also have the best time of purchase. The delivery took place - typical Amazon - fast.
