The Sulo Bio-Boy fits in perfectly under the sink. I have to buy my matching 10-liter paper bags. Since these do not quite fit into the bucket (are a little too long above) and the low-Biotüten tear quickly, I cut up from about 2 cm. So far I have seen no unpleasant odors. In the event that there is still müffelt times, there is determined as for Sink also Deo`s. I'm definitely satisfied with the quality of the "collector" and would buy it again.
