That's a powerful collar. My dogs is like a bad static shock at best. I too made sure I tried it before investing in it.

For me, it's a Godsend because it keeps him from heading down to the seafood buffet that is our shoreline and coming back all round bellied, sick and stinky.

Very humane too as I don't think he ever goes by the warning beep so his total shock count is like two from the couple I had to let him experience during initial training. Sure beats him being sick or worse.

With great power comes Awesome irresponsibility.
