We purchased the disc as an add-on to the Innotek invisible fence system. One dog learned to open the cabinets in the kitchen so we needed a solution. The shock is mild but definitely uncomfortable (I tested it on me before I used it on the dogs).
While it took some time to get our 2 dogs conditioned to the underground fence and the remote trainer, the disc worked intermediately. We’ve had one disc for a couple years and plan to order another disk to keep one dog out of the rabbit cage. He can’t tell the difference between dog food and rabbit droppings.
