Review title: Pain
Product review: I installed the battery and then pressed the button that is suppose to help repel a dog or get him/her to stop barking. I immediately got a terrible pain in both ears and then got an awful headache. I rarely get headaches so was surprised to get one so quickly right after I pushed the button. Now I am afraid to use the Dog-Off since I do not want to have that pain again. It is now 30 minutes later and my ears are still in terrible pain.
