I bought the Clorox Toilet Wand System a while back and have found it to be very useful. Once you buy the wand, it is only necessary to buy the refills thereafter, which cost around $5.00. This system does a great job of cleaning the bowl, and your hands never touch the cleaning pad. You just push the tip of the wand onto the pad, and when you are through cleaning, you just push the button on the wand and eject the pad into the trash. Couldn't be more simple. When you first buy the wand, it comes with six disposable cleaning pads. I like the fact that I don't have a dirty toilet bowl brush sitting beside the toilet, loaded with bacteria. The cleaning power of the pads is really effective, and I have always been very well pleased with this system.
Update On Mar 02, 2010: I am still using the Clorox Toilet Wand and think this product does a good job of cleaning and sanitizing the toilet bowl. I do sometimes have a problem picking up the refills at Walmart, but that is the only downside I have found with this product.
