Good product. Like the no-need-to-syphon water container
Good product.  Like the no-need-to-syphon water container, and the board has edges that keep the water from dripping off the side.  Only used it once, so need to work out some issues with the angle of the board and toilet to make it totally leak proof.  It's a bit pricey, too...that's why only 4 stars.  But best price and option I could find.
Rating: 4 stars
