The written instruction were not as good as some of your other products. A bit hard to follow. Would be nice if could down load complete menu down to a spread sheet such as excel.

This is a great resource tool for my students. They can just go and plug in numbers and convert. I do teach them the pencil and paper way first, but then I bring this out ans they love it.
