Blocks up drain
Having purchased and installed easy to fit and nice feeling you’ve cured the vermin problem.But after time because there is a lip for waste to get over it eventually blocked the drain.if you have a vermin problem don’t go for this cheap option go for a more expensive stainless steel one with no lip because after you’ve paid to get drain unblocked it will work out cheaper
