Initially the unit was super. Very satisfied until a month ago. Suddenly the instrument was no longer on and started his own business. Went to on their own and no longer made. When the battery was empty and recharged, the game went all over again. About Amazon I can no longer send back the equipment. Since it is a "Button function" is the only, I think two weeks, will be disabled. Would be glad about a new device, there are actually still 2 years warranty on all electronics or am I wrong?
Hope the Amazon soon comes into contact with me. Once this happens there an update.
