Report "I purchased the Roborover for my grandson for Christmas, I installed new batteries that morning and it worked great. But when he tried to play with it later the same day, it had stopped working. I am just getting the chance to check it out. I changed the batteries and it still isn't working. One eye lights up and that's it. Can you help me? Sincerely Lydia Anne Watson. P.S. he really loves this gift"
