I got one of these from a friend he just gotten 2 new 3000 mah instead of using the recommended 1200 mah. He said it worked great but while using for the for 3rd time the point started disappearing as if the lens was melting, and after further inspection, that's exactly what happened. My question is does anyone know of replacement peices like a new lense or better yet a new price to screw on lol. In the meantime I got the big black lightsaber size laser , supposed to be the strongest they sell and not a toy anything within 6 ft burns lol
