does not have much, but one thing they should at least reliable, namely to be stable and clean. Before the bristles just somehow could get aging, the brush on the brush head and handle connection is aborted. My first broken toilet brush !!! Sooo "long" has held no toilet brush with me! Result of it all was that I was allowed to take off the toilet to clear the brush head against the pipeline. Do not worry ... it was fortunately in the course of a bathroom cleaning! ;) Now I have a toilet brush from the hardware store, more expensive, but also much more stable!
