Product review (3 stars): Serviceable
We do a lot of laundry with five people in the house, and the laundry sink had clogged with lint several times.  One lint trap will last us two to three weeks before filling up too much, and I wanted a cheaper source.  These are of lower quality than the brand my grocery store carries.  For example, they are unravelled at the top just apparently from the packaging process.  However, they last long enough to catch lint and prevent clogged laundry tub drains.  I'd say they are worth the money if you go through a lot of these.

As a side note, the photo shows loose traps.  They are actually double packed in a retail box with a pink cardboard back.
