As some of the other post have stated, I use mine for when I have to dump at home which is not often, maybe 2 times per year, some might thing it is costly for two time per year, but I dont because it save me the frustration of pulling the 5er to a facility that has a dump.
It is not as fast as using the 3 inch dump hose, and if you are pushing it a long distance down a 1" hose you can do the math.
Also you have to be carfull on what goes down the toilet too, no flushable baby wipes, just TP or other material that brakes up with your cemicales. otherwise it will rap around the chopper blade and not work properly, then you do have a problem,
Other than that, I like mine, but if you are in a hurry to dump it's no race horse.
