        As with advanced calculators there is a learning curve. If you invest some time in discovering the features of the calculator you'll have a very powerful tool in your hand. It is also intuitive and easy to use once you go trough the learning process.

        Powerful device with most features needed to perform advanced math calculations. Very good price, good battery life.

        Printing of symbols and characters rather small. Also the instruction manual uses a small font, making hard to read. You'll need to wear your glasses.
