Sharp Electronics 8-Digit Twin Powered Calculator (EL-243S/EL-243SB)

Great to drop in messenger bag/backpack/briefcase or even carry in portfolio. 8 digits handle most calculations. Three key memory (m+, m-, cm). square root and percentage keys. Standard calculator, battery/solar powered. Good price. Should last a long time. Button size generally good fo such a compact calculator. Blue soft buttons on a light grey background.

I love the size of this calculator and the hard protective cover keeps the device clear of dust and debris when packed in my briefcase or purse. The buttons are the perfect size and the display is very clear.

I first got this calculator model some thirty-odd years ago. It still works, I have never changed the battery, and the solar panel is great. Even after being in storage for several years, it charged up off the solar panel in the ambient light in the room and was working in a few minutes. It is thin, light weight, easily fits in a pocket or pencil case, and does the basic computations. I most recently bought this one for my toddler niece who wanted to keep my original, but I didn't want to give it up because I still use it for quick computations at my desk, even with my (much more powerful) computer around. The display is still clear, the buttons are much more responsive than many of the "dollar store" varieties, and it has a useful memory function. Being limited to the basic four functions (addition, subtraction, multiplication, division), this is definitely not a substitute for a scientific calculator or a graphing calculator, but if you just want to tally your bills or check your addition on your homework problem, this is just the thing. The new model is nearly unchanged and even came in a nice little protective case. My niece loves her new calculator, and it is perfect for her to learn her numbers and basic math. I hope it will also serve her well for her studies and basic computations as mine has for me for many years. Mine has certainly stood the test of time!

The best thing about this calculator is that it's got a cover that latches. No, it doesn't lock, but that little hard-plastic door closes over the keypad, so when I toss it into my briefcase and head out, I don't have to worry about damage to the keypad, or the thing being turned on and staying on as a stray pen or something just keeps pushing its buttons. The main power source is light, but it's got a simple battery backup, the batteries being accessible when you pull two small philips-head screws from the back of the case.This thing is small and mobile, and is perfect for my mobile business needs. I'm not going to be plotting spacecraft trajectories or formulating amino acid degradations today, so I don't need anything more than the basic arithmetic functions it offers (as well as %, square root and basic memory functions).The buttons are just the right size, not so big that I feel like this thing is a learning toy for a 2 year old, or has been made for the myopic over-70 set. The buttons are big enough that I can quickly tap out my work without mashing down multiple buttons.To conclude, if you want a small calc you can tote with you and that will not let you down by running out of power, this is the one. If you're after a reliable little machine to crank out your daily checkbook totals or to tally up the pro-rating on your timesheet entries, then this is the one you want. Recommend.

I needed a small calculator to carry in the glove compartment of my car so I could keep track of gasoline consumption. This works great, is easy to use and takes up very little space.

Nice little calculator

The calculator works great but, it wasn't exactly what I was looking for. It's well worth the price 😄(I was actually looking for a wallet, super thin, checkbook calculator and the ads through me off.)

Just what I needed for work
