Excellent must have product
The entire product is made of soft silicone so it easily fit in the plastic outer ring . I made small hole in the cover of the lid of nanny trap . And this product easily slipped in that hole. It's very useful product and stops bad smell from flowing in reverse. That's why I am giving this 10 out of 10 🙂

Excellent quality and solved my long pending kitchen drain issues.
The product is quite good, and for the price is completely worth it.Fits the normal kitchen drains perfectly, though might be difficult to put in, since the kitchen drain sizes are not standard, the flexible holders do a good job of keeping the valve in place.
