The TubShroom hair catcher is just another TV gimmick. It feels cheap, is nothing more than plastic. The packaging states it is designed for 'standard drains', which it says are 1-1/2 inch drains. To install it, you have to remove your drain cover in some cases with older bathtubs. But if you have anything decent in your tub, especially a 'pop-up drain cover', you will not be able to use this at all. This was such a waste of money.
