Top favorable review
One of several calculators I would recommend to others.
This calculator has many features for my studies in mechanics (among other interests that interest me). I used to own this calculator model in college, but this has added features.

A must have for electronics engineers.
Never lose track of you're decimal point again thanks to the Engineering Symbols. This is the best feature. The second best feature is the stored physical constants.

I had one of this calculator and it is great. The two ways power has permitted that my other product working for eleven years and never I changed the battery. Moreover, I like because permit use the brain for thinking how write the operation, on the other hand the new type of calculators don´t permit it because give all.
