Review on PetSafe Stubborn Fence Without Wire by Melissa Dallich

is available. It hasn't been installed for a very long time. The adjustment range of the correction force is very useful, indeed absolutely necessary. Using an old fence controller (another well-regarded brand) I was able to test it by placing my fingers on the pins and walking to the fence line. This one comes with a no-touch ad, but it's for smarter folks than me. Initially, I set the strength to 5, which almost blew my arm off in a jet rush. I believe setting 5 will stop the elephant. 3 is more than enough, even for a big dumb dog (or a dumb plumber using his fingers as a test device). I can't say anything about durability as it hasn't worked that long. Find out sometime in a year.
