I love this BrassCraft Black Bellow Plunger! I hate having to use it, but when I do I know it is going to work the way a plunger is designed to work. Unlike the other type that has a cup that must be aligned just right over the hole so a proper seal is obtained, this bellow type plunger forms a seal with no guess work because when the bellow is inserted it fills the hole creating a seal that enables the blowing and vacuum effect to release and move the clogged material down into the drain pipe to be flushed away. When it comes to choosing a plunger, I highly recommend this BrassCraft Black Bellow plunger. It makes the ugly job of unclogging the toilet a much more pleasant and easier job. Performance This BrassCraft Black Bellow plunger performs flawlessly for me every time I have to use it. I have never had to plunge a clog more than two times before it is released and flushes. Scent Scent? Sorry but I know of no scent that is emitted from this plunger other than the horrible aroma of the clogged material in the toilet.
