You'll get a variety of opinions on this subject, some of them quite passionate.

I personally don't like it. It works by hurting the dog's ears. I'd prefer to try to decrease your dog's barking by management and by teaching a "quiet" command.

Barking is a difficult problem, though, more in some dogs than others. If all else fails and it gets down to "me or the dog", I think the bark solver is more humane than rehoming the dog or using a shock collar.
