Excelente producto, facil de instalar y muy efectivo

Haven't installed them yet. But using one of the starfish looking white drain cover in our shower and hope it works to keep down the bugs.

didn't work - smell and roaches still thru - my opening was a little larger than 2 inches so perhaps that's the reason...
