I had to once again grow me in my old age a calculator. I had quite a few in use but this has me baffled positive. So far I could not find a large Macken on the device. The key assignment opens up almost intuitively and for "normal" calculations without programming the calculator is really great. Especially the function formulas quasi how they can enter are on paper, coaxed me regularly a smile. It's all true, keys feel adjustable contrast, cursor key in the middle, etc .. Only the frequently used items such as Pi and the percent button must be selected with the Shift key, you could complain about. But that's about it. Really a great computer with good feel to a very fair price. Who does not need a programmable computer should access here.
