Nice size very accurate easy to use calculator
This is the nicest little calculator. It looks expensive. The numbers are clear and easy to read.. The buttons are just right. I love the fact that it’s silver not black. I lose things like crazy so I bought a couple, but I love this one the most. I’ve been searching for it for a few days. I will find it. It’s very accurate. Great deal for the price free shipping. Yikes it’s great.

Great valvue, long lasting
This calculator has been my go to for 30 years. It's works well, good battery life, and very durable. It has a vinyl cover to protect the key, the screen easy thread with out glass, and keys hold up in a dusty shop. I use have used them it in a factory setting as well a wood shop. A Good product at a good price with a proven track record. Win win

Simple, dependable calculator
It's hard to find basic calculators at a great price. Everyone wants to sell you advanced functionality that you'll probably never use. This has nice sized buttons and adding and subtracting as part of a continuous calculation is a snap. Love it.

Reliable and Affordable Basic Calculator
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.

A timeless design
A model I have been using for some 25 years. Dropped in bathtub/left out in the rain, just dry and reuse. works good if sub freezing temps. Battery life good. I replace as button fails and case breaks if stepped on.

A Classic Casio!
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!

This is a good all round calculator which does what it says on the pack. It seems to be pretty well made and is functional and practical to use. It is ideal to uses for travels etc and can fit easily in your pocket.

When I bought this in August of 2014, it was much cheaper. But honestly, I would still buy it again at this price because it is reliable and works perfectly. I've used this for many of my university exams and it has always worked fine! The program I'm in restricts us on the type of calculators we use, so no scientific, smaller than the size of your hand etc... so this calculator was perfect for me. I'm also paranoid that solar powered or battery powered calculators will die on me during an exam, so I love the dual power on this thing.

A cracking little calculator and absolutely perfect for me. The sleeve helps keep the keypad clean and protects it from accidental damage. I can chuck it into a drawer with all my other paraphernalia knowing it can't get scratched or squashed. Great value for money. I've had Casio calculators before and they've lasted for years. I love this one.
