[Number 6]

Guess what Ceaser Millan sells on his web site?

"The Illusion Collar & Leash Set is designed to allow the owner to walk and train the dog using a slip collar correction, without having to stop and realign the collar to the proper position. It provides the ability to give a firm, yet quick and gentle, correction that eases up when the pressure is released. A normal slip collar falls to the base of the neck near the shoulders, which does not provide as much control."

The electronic collar gives a gentle correction. Yes, I said gentle, much better than the old "choke chain" that was commen in training (and still is)! Again, if you are unfamiliar with this technique, you might not want to be so quick to judge it.
