Bests & Worsts Reviews from Amazon

I was a little nervous buying this because of how low the price was. I wasn't sure if I was going to buy something that would ultimately malfunction of glitch out on my dog. I've had it for a few months now, and it's been working great. I couldn't be any happier with the results. Only knock I have on it really is the settings go from 1-100. My dog reacts pretty harshly on 10 I can't imagine what it would do to her on 100. Other than that, it's done everything we wanted it do for our Farm dog.
