My favorite mother-in-law told me about this little gadget and its value in de-clogging drains. I admit, I was hesitant, but I dutifully went out to home depot and picked one up. That was a few years ago. I finally had to buy a new one as the teeth on the old one were starting to wear, but this tool is by far the best product I have ever bought. It performs its job perfectly, is simple in its design, and costs 2 dollars! If you have women in the house, or you are the woman of the house, go get one of these.
