## Customer Reviews

### ⭐⭐⭐⭐ Great just for the Greek prefixes!
*by F***S on September 3, 2025*

Have been hooked on calculators with Greek prefixes since I got the first one with that feature back in the Radio Shack days--probably a rebranded Casio. Saves tons of key presses and mistakes in electrical engineering calculations. This is a good replacement for the fx-115MS, however the construction feels pretty light and cheap compared to the older ones...
