I ordered this product and get the refill of Petsafe. From the article description does not state that it is the cartridge of Petsafe. As is shown in the photo Innotec, I also assumed that it is the refill of Innotec. The spray head of Innotec does not fit properly on the cartridge PetSafe. It was sprayed twice, and then the money was empty. The figure should be changed.
