Hi my friend I want to buy want of this. Question my friend bought it and I like it. So he let me try at my tub. The different is his will stick out the drain hole half inch . so water can drain faster. But my drain hole work different it won't stick out sit up it go all the way down when shower. And water drain very slow . Then I realize his drain hole inside had some metal pieces like a cross or X drain that why when but it inside it will help to hold it to make it stick out sit up . but my hole is empty inside and deep. That why it go all the way down. But if I put the tiny Long needle between the tubshroom hole it will hold the thing to stick out and won't go all the way down. Not sure is a good idea. Afraid it might not catch all hair. And don't want clog in the future. Not sure does this thing meant to be make it for cross drain and not for the empty deep hole like Mine can u let me know. So I can buy or not thanks Check the picture hole that I mean thx
