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

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.

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

great product. does the job

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.

THE CASIO SL-300SV CALCULATOR IS A NEAT AND NIFTY LITTLE MACHINE FROM CASIO. It has so many of my own "most desired", features, (many of which were more common in older calculators), that I wish it had them all! It is small enough to fit in your hand, and comes with a vinyl wallet, reminiscent of the leather or leatherette wallets that many calculators had in years passed. This wallet comes UNattached to the calculator, so that the user can attach it any way he or she likes -- an especially good feature if you are left handed, or wish the wallet to open with the calculator on the right side. (There is, however, only one "pocket" in the inner side of the wallet...so if you do attach the calculator so that the wallet opens with the calculator on the right side, the "pocket" will be hidden and slightly more hidden...which can be an advantage, if you want to keep things in you calculator wallet pocket even more secret and out of reach!) This 8 digit calculator has my preferred "picture-frame" numberic display at the top. I prefer the indented "picture-frame" numeric display to the seemingly more common, "wrap-around windshield" numeric display in many other calculators, because it somehow looks better to me -- and, more importantly, the "picture-frame" display seems to show numbers darker than the "wrap-around windshield" design numberic display. The display is bright - brighter than many other pocket calculators -- and has nice, large, dark numbers. Still, the display is not QUITE as bright as is pictured in the illustration. This is not unusual, as I have yet to find ANY calculator with as bright a display as is shown in a commerical illustration. However, this calculator's happily really bright display does come close! It has a sign-change key, a per-cent key....and an OFF key! This "OFF" key can save a great deal of battery use -- and it's really needed here. More and more calculators today are, (sadly for the customer), designed to have their batteriss changed ONLY by an "authorized dealer" -- much like watch batteries are. This is also the case here -- the wonderful, but now old-style "off" key, (happily making a "come-back" on more and more calculators!), is on this calculator, (too!) Now, if they'd just add replaceable batteries to the newest calculators, as they did when pocket calculators had their start! I hope this happens....but at least this Casio SL-300SV DOES have an "off" key....and that certainly is a big step in the right direction! Also, this calculator stays "on" for approximately 7 minutes and 10 seconds, before turning off automatically. Together with the "off" key, this l.o.n.g... time between keying in the last digit and automatic turn-off adds greatly to the usability of this calculator! Thanks, Casio! (Nostalagia section...sigh!) Remember a time when watches ran mechanically and had no batteries? And calculators ran on "AA" batteries that could easily be changed by customers? Or, later, lithium-battery powered calculators where the lithium battery was in a nice little compartment with a slide-in, slide-out lid? Now, "planned obscelesence" has taken the place of inventiveness and value in customer-service...and we "customers" ourselves have been called "consumers"....as if we were little piggies in a pen, "consuming" foodstuffs to be fattened up for market. Ulgh! Give me the good old days of the '60s, '70s, and '80s! Almost as bad as these new expenses is the fact that younger people donn't even know these things ever existed, outside of studying them in history books. When I told my nephew about gas service-stations that nnt only had other people to pump gas, but who also cleaned one's windshields, restaurants which served water without its being asked for, and other conveniences I had witessed as a child, he asked me, "What planet are you from?" To which I had to reply, "The planet of the 1960s!"... Back to the 21st century..... Anyway, alog with the "off" key on this calculator, and the l.o.n.g... approximately 7 minute and 10 second time before automatic turn-off, there is also the more-modern solar battery panel...which further lengthens the life of this nice little calculator. Without user-replaceable batteries, however, the calculator will probably not last more than 7-10 years, (my own estimate), at which time, either a personal trip to, or sending the calculator in by mail to, an "authorized dealer" in person, will be necessary for a battery change. Of course, considering the cost of these things, (especially 7-10 years hence), it will probably be in the customer's financial interest just to buy a new calculator. This is what all calculator manufacturers seem to want, now -- but I'm very grateful for that "off" key in this Casio model, and the fact that the "off" key, once a normal feature on every calculator, seems to be making a comeback on other calcultors, as well! There is a "square root" key on this calculator -- but no "percent" key. This is OK with me, as for a long time, I've felt that the "percent" key was somewhat of a superfluous one. To find percentages, after all, is a simple operation on any calculator -- even without a percent key. (To find, for example, 15% of 250, all one needs to do is press ".15" x "250". Then press "=". Voila -- the answer is: "37.5". To find out what percent 37.50 is of 250, all one need do is press "37.5" "./." (the "divided by" key) "250"....to get the result of ".15". So, I don't really miss the "extra" percentage key here, and one less key makes for an easier-to-use keyboard! The "face-plate" of this calculator is in very pleasing light-grey plastic. Or is it metal? I can't really tell...but it does reflect the light. In any event, the light grey gives a nice, "finished" sheen to the faceplate, and also gives a more relaxed and happy "look" to the calculator, as a darker colour, (black or brown), would not. The keyboard here is very slightly crowded, and does take some getting used to. But not much. The somewhat-too-small key are slightly convex, (rounded), rather tha slightly concave, (indented), and this adds, again VERY slightly, to difficulty in using the keyboard. However, this inconvience is very, very slight -- and the "off" key, the big, "picture frame" display, and the included wallet make this getting used to the very slightly, (and I do mean VERY slightly), cramped keyboard definitely worth it. Slightly larger than a "mini" calculator, but still easily carried in pocket or purse, with a solar battery, a lithium battery, a nice little wallet, and a very welcome "off" key, this is definitely a calculator worth considering purchase -- for home, school, or 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!

Works like it should. Handy size!

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.

Excelente

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.

Great quality for the price. Highly recommend.
