Please save your money and do not buy this.Like others, I also fell for the advertising hype and went out and bought this thing. I have a newborn, a toddler and a new puppy at home, which doesn't exactly leave me a lot of time to clean. So needless to say I had high hopes for this product.Well, to start with my shower was not exactly sparkling clean but not very dirty either...this product did NOT clean the shower and certainly did not prevent it from getting dirtier. It does not clean the wall on which it hangs, it does not reach above face level, and it does not even reach the far wall of my shower, making it pretty much useless. The refills are ridiculously expensive and the cleaner has a strong, offensive odor when combined with the steam from the shower. I can't even finish getting dressed in the bathroom without opening the door to get a breath of fresh air.Anyhow, I would rate it zero stars if that rating existed....guess it's back to cleaning the old-fashioned way.
