CasioCasio SL-300SV Standard Function Desktop Calculator | General Purpose | Large 8-Digit Display | Pocket Size | Basic Math Functions| Ideal for Home & Office

What can I say more than it's truly a classic?!Seriously this calculator I've used the same model decades ago when my dad carried one with him and I needed some help with school work in elementary school (I'm getting close to 40 now). So when I seen this was the exact one I remembered, of course I had to get it.Casio makes great watches but they excelled at making great calculators. This is an easy to use, basic small portable calculator that can easily be pocketed or stored away. The buttons are plastic but feel right and has that classic look that never changed with the silver aesthetic. And it has a nice "CASIO" embossed vinyl cover which can be affixed to the calculator permanently allowing you to keep it secure while on your pocket and not be accidentally turning it on and running the battery down, but also to keep it looking great for years to come.It's dual powered so there is a solar panel so it'll work even on a dead battery as long as it around a light source. But the fact it does have a battery means even in low light conditions you can still use it no issues. The display is only 8 digits but for basic computing, it's all you really need.This design by Casio has truly tested the sands of time and to see to this day they are still selling the exact same model goes to show that if isn't broke, don't fix it.If your looking for a classic calculator that won't let ya down while also being extremely affordable, look no further than this recommendation of a calculator!

I still use this occasionally. It's always ready each and every time I've turned it on since I bought it 10 years ago. The solar power really helps. I've never had to change the battery. Easy to use. The screen is large enough to see without glasses on. Buttons are nice sized so I don't fat finger and press the wrong ones. I like the mechanical feeling of buttons/keys. I don't care for flat electronic buttons (like smartphones have these days). It's a basic, but nice calculator. Happy with my purchase.

Design:Wanted one that has +/- function.Ease of use:Not too small or overly large.

Works like it should

I've had one of the SL-300 calculators for about 20 years and when it finally needed a battery I figured it was time to get a new one. BTW, the solar still functioned, but it needed light, which wasn't always that good. Anyway, cheap enough, I bought 2.

I purchased several of these calculators for my kids to use at school and to have around the house in case I needed to calculate something. Yes, smartphones or computers have a calculator app, but sometimes having a physical calculator is handy.These calculators are inexpensive, have the standard, basic functionality one expects (addition, subtraction, multiplication, division, square root, and a simple memory).The box includes a handy little flip cover to protect the calculator in a pocket or backpack. No manual is included, since its functionality is very basic.Calculations are quick and accurate, the buttons are comfortable to push, the screen is clear and bright (contrast is non-adjustable and there is no backlight), and the built-in solar panel and replaceable battery provide ample power for years of operation.

Works just as it should , light and thin, but nice size buttons and large, bright numbers.

The Casio SL-300SV is a solid, no-frills calculator that gets the job done. It’s compact, lightweight, and easy to carry around, making it great for quick calculations at work or on the go. The dual power (solar with battery backup) ensures it works even in low-light conditions, which is a nice feature.The buttons are responsive, though they feel a bit small if you have larger hands. The display is clear, but the viewing angle isn’t the best—you may need to tilt it slightly for better visibility. It’s perfect for basic math, but if you need advanced functions, you’ll need a more specialized calculator.Overall, it’s a good value for the price, especially if you need a simple, reliable calculator for everyday use.
