I've been using the OSALO Desktop Calculator for a few weeks now, and it's become an essential tool on my desk. The large 12-digit display is a game-changer—no more squinting or leaning in to check numbers. The fixed 30-degree angle makes it perfectly readable at a glance, whether I'm crunching numbers for my monthly budget or double-checking receipts.

The jumbo buttons are another standout feature. They're responsive and have a satisfying 'click' sound, almost like typing on a mechanical keyboard. It’s oddly satisfying! As someone who occasionally fumbles with smaller keys, these big, well-spaced buttons reduce errors significantly. Plus, the ABS plastic body feels sturdy—it’s survived a couple of accidental drops without so much as a scratch.

I appreciate the dual power source (solar and AAA battery). Even in dim lighting, the solar panel keeps it running smoothly, and the auto power-off feature is a nice touch for forgetful folks like me. The memory function is simple but handy for quick calculations without rewriting numbers.

One minor gripe: there’s no dedicated 'off' button, which would’ve been convenient. But honestly, it’s a small trade-off for an otherwise flawless basic calculator. If you need something no-nonsense, durable, and easy to use—whether you're an accountant, student, or just managing household finances—this one’s a winner.
