Perfect – powerOne Scientific and Graphing Pro Calculator Review

Couldn't be happier. It is very well thought out. The large keys with switchable screens make mistakes very rare. The landscape mode saves key strokes by putting more keys on the same screen while keeping the keys fairly large. Programmability is very useful and easy to use. Highly recommended. The developers are very responsive.
