we obtained this to prevent clogged drains.  its easy to install. the package shows several different options of drains and how to prepare prior to inserting the hair catcher.  ours was an easy to remove drain plug and not complicated at all.   we cleaned out the drain and easily inserted the hair catcher. it was made of rubber so bends easily and sits inside the drain with no issues.   it is easy to remove and clean out the trap.  after only a few showers we were able to see that it was catching hair.   a house with three girls with long hair this is an easy and affordable way to keep the drain clean.
