Title: Works like a charm
Review: This product is amazing. I have a jack russell that is so smart he knows how to get away with just about anything. He evens know when his collar is off he can misbehave. I've only had to use the shock feature a few times, and now he obeys commands with just the sight of the controller or the warning function beeps. The only time it doesn't seem to work is when new visitors come to the house. Still working on training with new people, but I'm sure if I spent more time he would get it eventually. The only reason I graded this product a 4 is because I wish it had rechargable batteries.
