mine only has the negative tone and tone with correction so I can't say anything about the positive tone only...
when I put it on him the first time I only used the tone to see how he'd react to it. he cocked his head to the side and looked at me like "huh?" but continued barking at the doorbell a few seconds later. i let him get used to the feel of the collar and then took it off.
the second time I had it on him we were in the car and he was barking and shrieking. I said "no" and hit the tone only and it didn't break his behavior at all. I said "no!" and hit the tone with correction and he yelped and hid on the floor and stopped barking immediately. he then jumped up in my lap and sat there with his eyes half closed, relaxed. which is a FAR change from the mess he usually is when the car is stopped (usually he panics and whines).
the third time I had it on him we had people coming over. he went on a barking fit and ran out the door as soon as it was opened so I said "no!" and pressed the correction with tone. he ran back inside and hid under the bench looking at our guests but not barking.
every time we've had it on him so far since, we've been able to use the tone only. usually we don't even have to use that, just having the collar on makes him behave. if he has it on and someone knocks at the door, he might let out a few muffled woofs but nothing like the hyperventilating panic barking he was doing before. when people are over he calms down a lot faster and will lick their hands or allow them to pet him within a few minutes. The thing with him is that we've removed that adrenaline "high" he was getting from his behavior when people came over before so his mind is learning a LOT faster that there's nothing to be afraid of when we have guests.
i've also found he's a lot more responsive without the collar all of a sudden. he was barking at the neighbors the other day and I said "NO!" and he whipped his head around and looked straight at me, I was shocked (no pun intended). lol...
so that's the method we're working on so far... he clearly understands what the negative tone means so I'm hoping we'll be able to phase out the collar within a few weeks because he's starting to associate what "NO!" means as well.
I would have loved to do clicker training with him to reinforce POSITIVE behaviors as well, but he was scared of the clicker when we tried it. Maybe there is some other noise or device I can use.
I wish there was a way to make the same noise the collar does without having the collar on him later on. With the negative and positive tone it would be like having a remote control dog
