The right rear wheel of my Rovio always spins at full speed and does not stop when executing a spin. I believe this has been reported here before and seems to be caused by a failed optical encoder.
I reported this to Wowwee over 3 weeks ago. They said at that time they are "working towards a solution" and would get back to me in a week. Since then they have been uncommunicative and have provided no additional info. My Rovio is in warranty (at least it was when I reported the problem) and I have been unable to use it all this time. I would think they would at least offer a working replacement in the meantime but they have not responded to my request.
Does anyone have any more information about this problem or insight into what Wowwee is doing about it?
