Review: IT WORKS!!! - We had the most awful smell coming from a floor drain in my business, and this product fixed it immediately. We cut it down to the correct size and it fits like a glove. No more bad smell! Buy it immediately if you have the same issue!
Review: Eliminated unpleasant smell from drain in basement - A drain in our basement was making our house smell like a sewer. We have a 3 inch drain opening, so I had to cut the product down to the 3 inch rung. The smell is gone and it was very easy to get it installed. I wish I had known about the product sooner. It is totally worth the money to eliminate the unpleasant smell forever and not worry about the drain being blocked.
