"Replacement cartridges are too expensive."
— Catherine D. (3/5)
"Very sturdy and well designed. I've had the product out for three weeks. Usually when I sit out back at night I will see about six or so rats running past over the evening. I understand correlation doesn't mean causation, but I have seen no rats in the last week. So between this and the poison (which never seemed to work on its own before), something is cutting down on their numbers!"

"Clear instructions Easy to use"

"I have 3 stations set up, the rats are drinking the bait. Waiting a few months to see a reduction in the populations. Very easy to set up and maintain. Only thing I'd like to see is a bulk option for buying the bait. Maybe a discount for buying 10 at a time."
