For many years I would spend a few dollars on a toilet cleaning brush and holder and really not think much of it. I had to do this quite often.What I have noticed through the last 10-15 years is that the metal used in the part of the brush that holds the bristles to the handle rust out so fast. This may also be in part that the holder of the toilet brushes I have been buying do not really have a way of quickly drying out, in turn accel..
I used this as a replacement head for my Oxo toilet bowl cleaner. I easily removed the old head and screwed this new one in place. No problems. It has worked well for me for the past four months and I use it at least once/week.
