This is, without a doubt, one of the best 'science and day-to-day' calculators you could ask for! It is compact in size, full function...from polar-to-rectangular, statistics, squares and cubes, nesting, and so much more. It is a 'dual-power' calculator, so the calculator can be used in total darkness (LR-44 battery required), though the solar cell will easily power it in any office lighting at night. The cell DOES NOT charge the battery, but Casio claims 3-years of use from one battery (using it one hour per day). It has a 'slider cover shell' to protect the calculator while in your pocket, too...and it 'bites' quite well...no falling off here. I purchased this after the Casio fx-82sx finally 'gave up the ghost' (with the markings worn off, keys chipped...the screen finally died). I wish Casio still made the fx-82sx still, but since they don't...guess the fx-260 solar is close enough. SOLID 5-stars, as most Casio products are! Definitely recommend!

purchased the Casio scientific calculator for my son, and it has been an excellent tool for his schoolwork! The calculator is incredibly user-friendly, with clear, well-labeled buttons and an intuitive layout that makes it easy to use for both basic and more advanced math problems. The display is large and easy to read, which helps reduce errors when solving equations. It has all the essential functions needed for algebra, geometry, trigonometry, and other subjects, and it handles complex calculations effortlessly. One of the things I really appreciate is its durability. It’s sturdy, compact, and fits comfortably in a backpack or desk drawer. The battery life is impressive, and we’ve had no issues with performance, even after months of heavy use. Overall, this Casio scientific calculator is reliable, affordable, and perfect for students and anyone needing a dependable calculator for everyday math. Highly recommend it for both school and personal use!

Received this calculator today. Seems to work fine. Keys are easy to read and there are several modes of operation , which, without the manual, one would have to just memorize. I do note that the Amazon "Product Information" is either misleading or just plain NOT CORRECT. Product Info says that 2 AA batteries come with this calculator, implying, I thought, that the solar cells charge an internal battery. Not so, unfortuately. So no light, no calculations. How long would it work when the light is low? Nobody seems to state anything about this most important "spec". Also, the Amazon Product Info says it's made in China, but the box containing the calculator I got says its made in Thailand, with Casio being a Japanese company.. Still it's a pretty decent calculator,especially for the price.

I love the fact that this calculator is solar powered. Since you are not likely to use this in the dark it is very convenient to never have to be concerned about whether or not the battery is charged. i have had one of these for quite a few years and it has never failed yet. The only drawback for me is that I used calculators from HP with Reverse Polish Notation rather than algebraic entry for over 40 years and it takes a lot of getting used to. But I know most people don't have that issue so this is a really good calculator for not much money.

I had a fx-995 "back in the day," and really enjoyed it. That calculator was super flat, and I frequently stored it in my textbook, yet its functionality took me through Algebra and into Pre-Calculus. I would like to get a new one, but Casio discontinued it a long time ago, and the eBay listings are asking more than I'm willing to pay. This calculator is essentially the same thing "under the hood," but in a more traditional calculator format: plastic shell with plastic buttons (and a squishy membrane under the buttons). I like having the same functionality that I essentially grew up with, but this one is shaped differently (thicker, but also a smaller footprint), which kinda ruins the nostalgia factor. The back as well as the slip-case is beige, which is something else that took some getting used to. I did find an Android app that mimics the fx-995 very well, but it's not supported on my new phone, which was quite a bummer. So I got this to fill the gap. It does the job quite well... I just miss my old calculator... and my age is showing.

I wish I could find one made in Japan, but this is my favorite exception. If it holds up, it qualifies as a superb little calculator.
