I've been using the OSALO Desktop Calculator for a few weeks now, and it's become an essential tool on my desk. The extra-large display is a game-changer—no more squinting at tiny numbers! The 12-digit screen is tilted at a perfect 30-degree angle, making it easy to read without adjusting my posture.

The big, responsive buttons are a joy to press. They have a satisfying 'click' sound, similar to a computer keyboard, which makes data entry feel precise. I especially appreciate the separate '00' button for quick large-number inputs—super handy for budgeting or tax calculations.

Durability seems solid with its ABS plastic construction. It survived an accidental drop from my desk (oops!) without any damage. The solar+battery dual power is brilliant—no more frantic battery changes during important calculations. Though I wish it had an off button to conserve power when not in use.

As someone who spends hours crunching numbers, the memory function and percentage key save me so much time. My only minor gripe? The slide-on cover feels a bit flimsy—I've heard others had issues with it breaking.

Overall, this calculator delivers exactly what it promises: reliable performance with excellent visibility. It's particularly great for older users or anyone who values comfort in their office tools.
