Thanks. Not sure about it, but I think part of the calc might be slightly misaligned or bent out of shape. All the keys except one row (x, 1, 2, 3) register and feel perfect. But that row doesn't really "click" and I need to press harder. Otherwise this unit is near mint, so I am also cautious about opening it up (which is something I have never done to any HP calculator).
