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.Verified purchase: YesCondition: New

The product is not working as expected and i m not satisfied with the product
The product has less visibility and hangs on regular basis as I have got my final exams now thats why I have to use the calculator. Otherwise I would not use it.Verified purchase: YesCondition: New

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.Verified purchase: YesCondition: New
