Review title: BAD
Product review: I thought since my dog is locked up in a small area this devise should work, but I was wrong. I would never buy this product and would never recommend to anybody. First of all the battery doesn't fit and I had to put a little peace of paper so it wouldn't fall out and would stay in place, which didn't really work well either. My dog doesn't bark too much but still this product didn't help at all, don't waste your time and money.
