Great for office use
Very responsive keys and the metal finish resists fingerprints well. Would give 5 stars if it came in more color options.

Perfect for my accounting desk
The large keys make data entry so much faster, and the metal panel feels very durable. The dual power feature is a lifesaver when the office lights are dim.

Best calculator I've owned
I use this daily for financial reports. The buttons have a nice tactile click, and the solar backup means I rarely need to change batteries.

Solid build, great screen
Really happy with the visibility of the 12-digit screen. It's slightly heavier than plastic models, but that just adds to the premium feel.
