Used once , lost it. Now have found it. I purchased to train my doberman pup.Had to buy another I misplaced this one, then got another dog so got the two pack. This thing was about if not more than 60/65 bucks. They work great! Can.lppk.up on amazon if want. I still use mine on my dogs, now grown if misbehaving. They know once it goes on they better mind. Has many different stimulations, & a beep. The beep works perfectly fine for my dogs. You will have to get a new collar as I have cut this one, that was to suit my pups needs at the time. They are 11 bucks on Amazon. This is a P620 collar. Its waterproof, long range, & rechargeable with long battery life. One of the absolute best collars Ive ever purchased for training. MUST pick up in Manchester CASH only No trades.
