Casio SL-310SV 10 Digit Display Basic Calculator with Protective Case

This little Casio SL 310SV has been through it all. I first picked it up years ago for my real estate sales exam, and it was flawless, quick, accurate, no nonsense. Later, my wife used the same one for her pharmacy tech certification, and it handled all her conversions and dosage calculations without skipping a beat. Fast forward again, I used it for my real estate brokers exam, and now it's in my middle schooler's backpack for algebra homework. This thing is practically immortal. The solar and battery combo means it's always ready, even when it's been sitting in a drawer for months. The buttons still click like new, the display is super clear, and it's small enough to slide into any pocket or binder. If you want a reliable, simple, and affordable calculator that can literally go from classroom to certification exam to business life, the Casio SL 310SV is a solid choice for over a decade. If it isn't broke, then leave the SL 310SV alone. It just works.

this little casio calculator is the perfect size to keep closeby whenever i need it.it's easy to use, %26 the number screen is easy to see. the buttons are large enough so that i don't press 2 buttons at once. the price is really worth buying this. i hope it lasts a long time.

This is the perfect basic calculator for government tests. I bought this to take a HAM radio exam as they only permit basic calculators in for testing and my other calculators are considered “too advanced”. This worked perfectly as it allowed me to make the calculations I needed.

I use this calculator at my work. it's oily and I drop it at least once a day. this is my second purchase for this calculator because it's tough. I bought this one to replace the one I've had for about 4 years.the only reason I'm replacing it is because I think I spilt something in it and numbers aren't very clear anymore. It's the first one I've had that last so long

It's just a basic calculator. I got a bit crazy with some back to school "necessities." It's great for younger kids who can't take their smartphones to school. But mine is homeschooled and a little older. She can use the calculator on her smartphone, and she needs more advanced functions. There is nothing wrong with this calculator. I just didn't put enough thought into what was actually needed.

I recently purchased this calculator because I needed one that was easy to see. In fact I purchased two of these. The price was reasonable, you can see the keys and window very good. it has a protective case and I like that. The keys are very easy to use. I am very pleased with my purchase of these Casio calculators.

over years i have had radio shack and kmart small solar calculators. this casio is by far the best. charges fast. the fold back cover is great. i can leave it on the desk without worrying if the keys are being damaged by sliding files on top. and the keys are large and with clear printing. casio is a good brand for all the items i have bought over the years.

Perfect little calculator for all those who don't use their phone. I owned a very similar one that outlived by far the others I had in different areas of my home. This is what to expect from Casio!

I've had one for about 10 years and apparently I stepped on it. It still works but I went ahead and replaced it. This site showed my store had it on the shelf but it was not there so i had it shipped with some other things not available in the store.

Not sure why or how you rate "buttons," there are no buttons. There are keys though. This was not a shirt I purchased. They should probably not allow grade school students to write the questions. Price was great and could be carried in a pocket. I don't understand what all the keys are for, so guess I don't need to use them. Otherwise it's seems to be quite easy.
