It has a little issue with the power switich but apart from that everything works perfectly. Does yours also have the brown leather case with the top flap held down with velcro? Mine was a little rough when I first got it but I was able to nourish the leather with some shoe polish. Current daily drivers: HP-41CL, HP-15C, HP-16C |
