Excellent poopy bags!
I've used them for over two years and probably gone through 600 bags. Never had one single defective bag. Very sturdy and no leakage. I place the knotted bags in a Diaper Genie, which has a hanging toilet bowl disinfectant in it, and I only need to empty it every 10-14 days into the trash.
Everyone should use the Bags On Board... real big dogs might need two bags, but that beats just leaving the poop on the ground!
ProsEase of use and effectiveness.
ConsBags need to be loosely rolled on the spool so that their inner surface doesn't cling to itself so tightly.
