The product is large and little heavy. My corgi enjoys it, still learning how to place the ball on the hole but we are getting a kick out of it.

Overpriced, doesn't work, spray some vinegar on the problem let sit over night and save your money! The vinegar works on lime and calcium, not sure about rust.

I bought the medication referred to in the book but have not seen any improvements from using it. The book made sense. I just don't know if the information is so accurate.

Getting this installed via Amazon was a major headache because their invoice provided the wrong information. What was listed as the Product Key was actually a Redemption Key which is used to get the Product Key.
