I purchased this mini Educator from Amazon to train my dog when I adopted her. We used it a couple of times but in working with a trainer we ended up not really needing it. E Collar is in its original box, like new with manuals and accessories. All the information is provided in the pictures and screen shots from the actual Amazon listing. I did purchase and change the contact points to accommodate my short haired dog but I'm including the original contact points which are appropriate for long haired dogs. The collar is about 22" long from buckle to end which accommodated my dog's 19" neck comfortably. I'm open to offers and please feel free to ask questions!
