We already changed brita 4 carafes of this model and we ras-le-bol. It is hyper poorly designed: fragile and unstable, it easily switches and breaks at the slightest touch. The walls of the decanter are too thin, in very resistant plastic. So its electronic counter breaks down very quickly, usually after only a dozen cartridges. Programmed aging? Too bad, the filters are good. Our first brita jug (with a mechanical counter) worked 6 years
