Honestly, if you're going to get an e-collar, this is a great one. Because it has 127 levels it has very minute changes from level to level, so you can really be precise about your dog's personal working level. Also, I always did love the LCD screen - many e-collars don't have that so they're not as exactly precise, level-wise. Because this has a vibrating feature, it could also be used for only that on deaf dogs to teach them a recall.
These retail for over $200. I'm asking $150, plus $10 shipping.
