The impressions about the "smell" are different. In the tiny drops of slightly Gästeklo chemical smell forward to, in much larger bathroom not. What bothers me it not. If any test for yourself times. Together with the insertion chute of Geberit a practical matter. Not to it miss more. Every now and then is a cube which decomposes too quickly and then for deep blue water makes. Marks on the toilet seat should be removed quickly, you do not get it otherwise more from. With us, however, the spectacle underside is only slightly affected in Gästeklo. For me anyway clear recommendation.
