Casio Wired White Calculator - Good Value For Money, Works Well, Quality, Sturdy
Casio Wired White Calculator works well. This calculator has larger buttons than standard machines, LED screen is clear with good quality display, speed of calculations and printing speed is good, and output is easy to read. Casio Calculator is wired unit but does have a compartment for battery which I haven't used. Overall I am pleased with this calculator because it is sturdy, good speed, has quality display, printing is fast and worth value for money.

I'm a practicing CPA and this is just what I needed
I've been a practicing CPA for longer than I'd like to say, and have used lots of calculators. I bought a calculator a little over a year ago from another well-known brand, and was surprised that after only a year and 3 months, the fluorescent display was starting to fade. I decided to take another look at what else was available. I wanted a calculator that was large enough, but not too large like some of the behemoths that are available. I almost never use the paper tape, but once in a blue moon that feature comes in handy. I didn't care about how fast it printed because I almost never print anything. And I wanted a machine with a good display that would last. So I looked at this Casio, and it's a great little machine. For one thing, instead of the old fluorescent display it has an LCD display. Nice, large numbers. Next, it has a built-in sleep mode that happens after approximately 30 minutes, thereby saving the display even further. It's easy to wake up the calculator - you just press the CA button on the left (which also says ON next to it) and that turns the display back on. I also like the layout of the calculator and the nice spacing between the keys. If you want to get a printing calculator that a long-time practicing CPA would appreciate, then get this one.

Perfect Desktop Size
I like the size of the calculator; not too big, not too small. The number keys are easy to use as a light touch does it. The size of the LED display is terrific; it's large and easy to read. Most of the time I don't use the print function, but there are times when I'm running a long addition (like at tax time) and I want a printed tape. This allows me to find errors quickly. I'm happy with function and performance, and would recommend it to others.

Good calculator.
Very nice calculator, love the display. Has a few more options than I really need but the price was right. Keys are larger than I am used to but I'm sure I will get used to them. Also like the auto shut off feature. Good purchase.

Great 10-key calculator
Working in an office for over 30 years, I’d always wanted one for home. This one is a little smaller than those huge ones at work so it doesn’t take up too much room. Love it

Great display and Large Keys!
The LCD display is a great feature! I choose this model specifically for the display. I also like the larger keys. They are easy to see and use. The tape prints subtraction in red which makes it easy to spot. There are many features for those who want more than just basic calculations. I highly recommend.

Easy to use
Love that this calculator is easy to use! Just plug it in and select whether you want it to print or not. It’s easy to read and I love that you can change the paper. Fits nicely under monitor stand. Noise is tolerable and overall performance is great. Excellent value for your money.
