2 returned R2's and 4 tried out in the store. All 6 units did not work. Yesterday my wife went to get me an interactive R2, (I told her it was really cool hint, hint),but when she got to TRU in Burbank CA, there weren't any left. She asked about them at the customer service counter and the manager told her that all 6 units they got in were defective, something about wires not being connected at the factory.(like a TRU manager would know) Is it a rare case or is there any other reports of this problems? I hope not.
