Okay, so I grabbed this 5-pack of Amazon Basics calculators on a whim during Prime Day, and honestly? Best impulse buy ever.

First off - the display is crisp AF. No squinting at tiny numbers during late-night budget sessions. The buttons have this satisfying click that makes you feel like a math wizard.

What surprised me most was how sturdy they feel for the price. I've had one living in my bag for months getting tossed around with keys and it still works perfectly. The solar+battery combo means I've never had one die on me mid-calculation.

Pro tip: These make perfect emergency gifts. Left one at my parents' house during tax season and now my dad won't stop texting me calculator memes. That's how you know it's good.

Only complaint? Now I have five calculators and keep finding them in random places like some kind of math-themed Easter egg hunt.
