Have this water filter for about half a year has passed. The water quality is truly outstanding. Devices not calcify and almost water tastes much better than fresh from the tap. The cartridges last a long time (one should they change after a month, but for me, the display always ran only after 2-3 months to zero). The display, however, is no longer usable after a few months and the battery can not move because the element is bonded. The very large deficit in this filter is for me the casting. It just keeps dripping beside it. Like a really bad pot. This is also the main reason why I am going to look for the exhaustion of the remaining cartridges for a new filter.
