Colander works better. It is easier to clean. Yes I use a colander, *LOL* To be graphic, put the colander right in the toilet and shit in it. When you are done, shake the colander and flush the toilet. At the end of the whole thing to clean the colander I pour a little bleach into the toilet and use the toilet brush on the colander. Gets the toilet and colander clean at the same time. Make sure no one gets ahold of this Liver Flush colander to use it in the kitchen, *LOL*
