Great for training your dogs and transform them into a master hunter or just your best friend. Top of the line quality two available they were a little strong for our little dog I'd recommend a lab or something that size. Work great first 200 takes them, chargers included with cords and boxes. Batteries hold great charge and the range is more than 1/2 mile for sure. These where 3 to 5 hundred new and have one season on them. Thanks Zach
