We just adopted a chihuahua who barks incessantly at the door. It's been impossible to have people over. I ordered PetGentle and got it within a week. I hide it in my pocket and always give her the opportunity to obey my "quiet" command before correcting her by pushing the button. I only had to push the button on 3 occasions, she now obeys "quiet" immediately and I haven't had to use it. I'm stunned. My dog is on the sensitive side, as well as extremely smart.
I think you need to use it immediately issuing a command if it isn't followed. Barking isn't bad. Disobeying the "quiet" command is what needs correction. That's what I've been working on with my dog.
Bottom Line: Yes, I would recommend this to a friend
