Query: IT STINKS!!!

it couldn't walk w/out falling. i tried it on hardwood and carpet, still keeps on falling. walking backwards was even worse. it wasn't what i expected it to be.i was expecting a more sophisticated technology and all i got was a piece of crap. i consider it to be "dumb".oh, the dancing, the burping and the farting? it's fun but i don't think it should cost that much...this thing can't even pick-up anything...i gotta hand it to him. what's the fun in that?we played w/ it for 20 min. after how many falls, i made-up my mind...i'm sending it back for a full refund.
