Not for me. I am helping a neighbor with basic OB for his rescue pup. He had bought a "Petsafe" brand training collar, (yes, the same as the invisible fence maker). At first glance it looked like it would do. I tried it out on me the other day before starting to use it on the dog. What a piece of junk!!! It has 8 stim strengths but you have to turn it up to 6 to even feel it. Then it does not "fire" half of the time. It is so very unreliable that I could not possibly use it properly or fairly and I told the owner I thought he needs to take it back and get something a little better. Are there any of these "pet" collars that are good enough? I am TT all the way on e collars. But I know this guy is not going to spring for more than $200. Any suggestions appreciated.
