yes I expected it was one of those 'things' you had to feed and take care of!lol
I had a little robot that way 3 years ago, a gift from friends..after 1 week it was driving me nuts, i just didn't have the time for it, i'd sort of get back home to discover i had to give him a virtual shoot as soon as possible as his eyes were infected with disease..lol he did last 9 months though before dying of a flat batterie....may he RIP!
