I find the Duftspüler really good! At the beginning of smell is very strong but it evaporates after some time something and no longer smells as extreme. In a larger bathroom, I find the smell as long as he is so strong good, but in a small toilet that is very strong. The balls I find visually beautiful. The Duftspüler can reinhängen easily and when unhooking him for toilet cleaning and laying on the ground, nothing drips out. We use it even in the Pissuar my husband. With the durability I am also satisfied, the thing holding us about 4-7 weeks, as we have for a 3 toilets and lately were hardly home. All in all I'm very happy with the Duftspüler.
