my skim mate smells really bad but only when I open the collection cut to empty then you wish you had not opened it. Ho by the way I open and empty in the washroom even with a fan on the smell lingers in there for 10 - 20 minutes. I am telling you its bad as it can get. but there is no smell other wise you can get a connection system they use a carbon filter on the vent hole. I am looking at building a couple of these just have to fine some acrylic tub to do this. There is a guy down on the coast that is selling some I know but I will not be down there till after the July long weekend. so maybe he will still have some.
