With calculators we can not say much in theory. You have already met the requirements depending on the model certain functions and if the are the dominating. In this calculator, I must say: TOP! Why? Well, for one it is cheap, portable, runs on solar power, so change batteries at some point and has a lot of features for the money. But what I find most of this calculator is that by holding the buffer of solar pretty good. Had it already repeatedly with my old that the case of bad light immediately ran out of steam. The even here ends in a few minutes by when abklebt complete the solar panel.
Pro: - Handy - Low - Many functions - Super energy management
Contraindications: - (Konnt I find nothing so far)
So for the money you can not expect real. I can highly recommend.
