I bought this screen to avoid that I regularly have to fish the remaining caught my girlfriend hair out of the drain. Unfortunately, this screen serves this purpose only partially, because it continues to go through hair and delays the rumfischen only by a few days. Appreciated I would say that 70% get stuck and the rest passes through. For me too much, therefore only 3 stars. The fact that no 100% achieved is clear to me, but at least 90%. Now I'll look around for a screen which still has smaller holes.
For culinary use certainly better to use than the shower / bathtub. Otherwise, the screen looks good, it just is not so very suitable for my purposes.
