That product worked just like it was supposed to, it's right in the name for fucksake - "NO CHEW DETERRENT", meaning it's NOT a chewing deterrent as in "NON CHEW DETERRENT". If it were it would be called "CHEW DETERRENT" or "CHEWING DETERRENT". This idiot paid for something that is specifically NOT going to work. Yet I'm sure they were surprised it didn't. This is what happens when idiots don't have a grasp on the English language.
