Product review (5 stars): Worked for me
The hardest part about installing this is cutting out the old one first. After that all you do it shove this one in the drain and you are done. It couldn't be any easier. You can easily pull it out if you need to, but it doesn't move or come out on its own. I like that it is a bit more closed that the original one because nothing at all splashes back up. I don't find that the water drains too slowly or have any issues with it, but if you want more water to pass through just cut some of the rubber off and you're all set.
