Product review (3 stars): I did not have good success with this product
I did not have good success with this product.  It may be because our laundry has so much lint in it that it overwhelms this product.  Our drain line backed up on the first use.  Again may not be the product fault.  Fabric softner really exacerbates drain line problems.  My family has to be really careful because lint combined with fabric softner makes for serious drain line stop up.
