Great rare collection puzzle
Collection item, I started this puzzle years ago and never got to finish it. I thought it was going to be extremely hard to find, but I got lucky and this one; unopened and in good condition

Fantastic
I've never had a graphing calculator before, but is working like wonders. Even my father didn't believe that was this cheap being from a well-known company such as HP, very good product. This calculator allows me to represent graphs in my PreCalc class, it lets me make simple algebraic operations, the interface is pretty nice; functions as well or better than other scientific calculators. The only things I didn't like were: uses batteries to my disappointment, it is hard to look for the right sub-fuctions of the keys (pi, exponent, square root) because of the colors, but I believe it overcompesates with the very hand usb port (and apparently a binary port) on the top.
