The previous oral irrigator with brush I had years and was always satisfied with quality and performance. Years ago I made a slip-up with another brand, which after a year with about Totakausfall ended. My partner had similar experiences with the same system. Now we both use this shower. However, the performance has been somewhat reduced, which hardly affects the effect, but me personally something bothers. Nevertheless, we do not always take Brown, already the quality wegen.Neuere techniques have us convinced.
