I just found a SuperYo Triple Play at a garage sale at the bottom of a toy bin for 25 cents. I did some research and found that it can be a looper or a sleeper by popping out the axle and turning the sides inside out.
It seems REALLY responsive, as i expected (about that of a Duncan imperial), but wouldn’t they make it sleep longer while in butterfly mode? It seems to sleep just as long in both modes…
