Okay first of all, when I opened it, it said to not put on ear phones. Then it said I had them plugged in when I didnt. And when I did, it made a loud screeching noise and lord knows this is not an app to download. It hurts really bad and now I have a major headache. The head phones made it worse bc I put it in my ear and that happened. I can still hear the screeching like its echoing in my ear and its been over 15 minutes. ALL I WANTED WAS A LAZER FOR MY KITTEN. YOUR BETTER OFF GETTING ONE CHEAP FROM THE STORE THEN HURTING UR EAR DRUMBS. THANKS A LOT. ?????????
