Bought new and used a couple of times. Did not come with a battery but we put one in.
Note: This item had good ratings when we bought it. But our hard headed Doberman was not in the least affected by it.. Maybe a smaller dog or one that is not so head strong, this might be perfect for them.
$10.00 FIRM with battery.
