8 digit, extra large display, dual power
The Canon LS-85H calculator does what a simple calculator is supposed to do quite handily: it easily accomplishes basic mathematical functions via a keypad with practical key size and has provision for memory calculations, working with percentages, and finding square roots. While it is limited by its capacity to work with only eight digits, this calculator should be adequate for simple mathematical duties. Push the LS-85H beyond it numerical limit, and an overflow function returns an error message and freezes the keyboard.
Measuring a little less than 4 by 5.25 inches and boasting a large, upright display, the LS-85H is easy to use, and is easy to read in well-lit rooms. Powered by a solar cell, the LS-85H also contains an alkaline battery which allows the unit to be used under most lighting conditions. Battery life is dependent upon usage, though once the alkaline battery is discharged the calculator can still be used on solar power. A new battery can only be installed at a Canon Service Center. To help conserve battery power, the unit automatically turns itself off if it is not used for eight minutes. A tap on the N/C key turns it back on. --Luis Uzeta

What makes this calculator so nice is you barely notice it because it allows you to concentrate on what you're doing. Sure it doesn't have lots of functions, just the basic ones, but I have another calculator for that. I tend to use this one all the time and I'd feel lost without it.
This is a remarkable, durable and useful calculator. I'm perform a lot of accounting in my job, and this is my normal go-to calculator. From the time I ordered it to delivery, only 13.5 hours passed. That's the fastest I've had an order fulfilled. Just thought I'd relate that.
LS-82z -- "want to be when it grows up"? Right! THIS calculator -- the Canon LS 85H calculator!``The smaller calculator -- also reviewed for me by Amazon -- is an excellent little machine. But I can see how its smaller size, (and in particular, smaller keys), would be a problem for those using it on a continual basis. Men especially, as they tend to have larger hands than women....
The slightly larger, Cannon LS 85H calculator, being reviewed here, is almost as perfect a general-purpose calculator as one can find these days! A handy size, which is at home either on desk-top or pocket/purse.
"Man-size" keys, which are still not overwhelmingly large, which a person with the largest hands, and also one with the smallest, can use
with the utmost of ease. The eight-digit display is large, and very well spaced. Nice little "extras", found in most -- but not all -- other general-purpose calculators: a percent key, a square root key, and a sign change key. (The sign-change key does not appear on the smaller, LS-82Z).
True, the larger LS-85H calculator has an enclosed, "wrap-around" display, (enclosing the entire top part, all together), rather than the "picture-frame" display, (in which the numberic display is indented, and "framed" by the rest of the top of the calculator) of the smaller calculator. (And I, personally, find the "picture-frame" display far more attractive). But the larger LS-85H calculator stays on for approximately 3 minutes before turning itself off...approximately a full minute more than the smaller machine, and this may mean more to many users.
About the only things missing from this calculator are an "off" key, (not found on the LS-82z, or on most other calculators, either), a "resume" key, (found, at present, only on the large and somewhat cumbersome Sharp (R) VX=2128R calculator -- but a feature that would be welcome on ANY calculator!), and a "live" battery, (you know -- an
"AA" battery, or even two --which can easily be replaced. Like they used to have when calculators first came out?)
Oh, oh...wait a minute! I see that Canon ALSO has, (or had), another model that looks ALMOST like this one does, but which has, as a model number, LS-85H 4050A001AA! Looking at the description of it....YES! It has a live battery! AA! Sadly, there was only one of these for sale......and, yes....this reviewer has done what the vast majority of people would do under the same circumstances....grab it! Hopefully, Canon will produce more of this "AA" powered portable calculator....as will all other calculator manufacturers! Replacable lithium batteries are just NOT easy to replace! (I see that Canon DOES have a larger, 12-digit "AA" powered calculator, still on sale! -- Canon 7438A003AA). It got one 3 star review....but if I wanted a larger, 12-digit calculator which uses a "AA" battery, I'd try this one for sure.
Anyway, the Canon LS-85H, which is the main calculator being reviewed here, is a good, basic, little machine, with size, keys, and basic features, that feel, and respond, "just right". Great for "Goldilocks", or anyone else you know -- even yourself!
Canon to the rescue. This unit has two wonderful features. (1) It adds, subtracts, multiplies and divides. (2) That's all it does. So when you're on the phone with someone, trying to figure out what the total is, you don't have to worry about accidentally getting the square root of pi.
It does the job. Easy to use. However, I now wish I had bought a printing calculator.
If you get distracted, you have to start over.
I would recommend this for the good sturdy product it is.
