I like that you can do all your calculations on one screen. You don't have to open up multiple screens, and if you need to make any adjustments you can easily do so without having to go back to the main screen. Sometimes it takes a while to recognize what you're trying to input. Maybe if there was a way to highlight specific values as they are entered, it would be easier to see what needs adjusted. Just do some quick research before purchasing this product. We use it in our shop to monitor critical production parameters.
