With internship colleagues, many of us have acquired this small calculator. For what nasty surprise to hear "prohibited programmable calculator!" And what she does, she does it well, especially the binary conversion, Hex etc. Main features for which I bought. There are solar cells (photovoltaic or should I say?), So probably the stack she held a "eternity" ... The design is nice, the protective cover that protects the essential, namely screen and buttons. It snaps behind (although I prefer sliding systems). Keystrokes is nice, I do not rebuke me several times, and the navigation pad is really comfortable to move on or between the 4 lines. In short, it is a good calculator that is enough for the various calculations required in IT, electricity, level math BTS see more. FYI, it is found without problems less than 20 in supermarkets, so small flat for the price on Amazon.
