I have a silicone toilet brush and the silicone toilet brush does work great at cleaning the toilet and I find it actually works better than my old toilet brush.
The silicone toilet brush bristles are a really great idea since they don't collect the water and let it drip into the holder.
The silicone toilet brush is much more sanitary and easier to keep clean and easier to keep the toilet clean with and I think it's a great toilet brush and would highly recommend them.
I would never go back to my old toilet brush now that I've using a silicone toilet brush for a few years now.
