It's the only pilot case I've found where the wheels are on the side so that it's upright when being towed. This allows the handle to extend further which is more comfortable for taller people. It also tows more easily through narrow gaps.
I needed a calculator with reliable x to the power y and memory functions for an investment examination. This was the only calculator I found which can do this in a simple intuitive way. All the others I looked at added unnecessary complexity which could lead to errors in an exam. The only thing I would change is the button size which is a bit small for my banana fingers. By the way; I passed.
