I bought one of these brushes about seven years ago and it is still going strong. I have changed the brush head a couple of times. This is very easy to do. I had no hesitation in buying a second one for another loo and wish I had done so sooner. You have to remember to change the disinfectant regularly but that's easily integrated into the routine of cleaning the loo. It is worth the extra cost in my view. It also looks good. A serious bit of kit which, with replaceable brush heads available, will last a long time.
