Product review (5 stars): 10 highly effective traps
Fantastic when used with in sink catch.  They catch most of the hair and lint, but done does escape.  I use an in sink catch too, which is a passion to clean, this saves me from having to clean it for six-ten laundry loads, saving me lots of time and lots of lint or hair making it into the drain of you don't have a catch in the sink.

I also did get 10 like the product post says.
