Nice, with one problem
The keys are well printed and feel solid in tactile sense and the functions are easy to understand and enter. The display is adequate and slide case built feels robust, however, I am giving a one star deficit for the conversion function (the primary reason I purchased this model) because it is unnecessary difficult deal with in its clunky interface.

Lacks basic functions
Lacks basic functions. For example the nth power of a number (X to the power of Y). Pretty useless except for very basic math.
