Is there already a troubleshooting thread already here somewhere for the infinity? Mine just stopped working. I made sure both sets of batteries are charged and nothing is happening when I push the button. I noticed it was acting like my ego does when the battery is getting low before it dies. I thought that was odd. When it quit I figured it was time to change the batteries. Nothing with fresh batteries. I recharged the ones that were in it......nothing. Is this a quick fix somehow? Thanks in advance.
