Negative Positive
Title: Cheap imitation
Review: This item does not hold the odor as well as the original cartridge that came with the litter lock unit I purchased at Petsmart. I bought this 5 pack unit to save money, but since it does not contain the odor it has been a waste of money. If this is indeed a legitiment item from litter locker, then they must have reduced the thickness of the plastic, which is causing the odors to escape.
Is the review positive or negative?
