Review snippets: Love these things. Controls dogs well. Very humane... no perpetual tugging on leash. You may have to zap your dogs once or twice while training them, but after that a simple beep (The zap level/ beep is selectable) will do / I was hesitant to try a training collar at first, but this one has really made a difference for my dog. The design is sturdy but comfortable, and it comes with multiple settings so you can adjust the correction level
