Product review (5 stars): Reliable and easy to use
Granted I wish my washer drained somewhere I didn't have to see it, but since that's not an option and since we just got new sewer pipes that I want to protect, these things are life savers to prevent tons of link going down my drain. I also use another barrier at the drain itself to really tackle it but these things alone do a great job. Love them and the convenience of the multi-pack. Should last all year.
