The rescue gave us PetLink, but an hour after it was inserted it came out and I found the chip just hangin' out in Ralphie's fur. When I took him back to the vet, the vet's office had HomeAgain. It hasn't come out (as far as I know). The only thing that bothers me about Home Again is that they spam me with junk mail about signing up and paying for their premium service.
