Customer Rating: - Sharp EL243SB Handheld Calculator .

I love this Sharp calculator.. I had a cheap one that lost half its display so I looked on Amazon to find something small, reasonabley price and there it was... Simple with a solar window and sharp 8 digit display. Bonus was the hard cover so I can put it in my purse to take it to the store. Nice. Thanks Amazon.

Customer Rating: - Ideal Calculator For Simple Operations
If you want a VERY BASIC, SMALL calculator that only adds, subtracts, divides, and multiplies, and has a memory, square root key, plus/minus key, and percent key, this is the one to get. Most important is that it has a CE ("Clear Entry") key: If you're adding or subtracting a lot of numbers and enter an incorrect value halfway through, you can delete it from the display by pressing CE without disturbing the calculations that you've already done. NEVER BUY A CALCULATOR THAT DOES NOT HAVE A CE KEY, because if you enter a wrong number somewhere along the line, you'll lose all your work when you press the only Clear key, which clears everything! (As you can tell, I made this mistake.) The buttons are a good size (not too small or too large), the calculator takes up very little room on a desk or in a purse or briefcase, and it calculates quickly. The cover is attached and unobtrusive if you just want to leave it on a desk. After nine months, the calculator is still working fine. At this low price, I'd have no problem replacing it once a year if necessary.

Customer Rating: - Really cheap calculator, but good
I bought 4 of these calculators so I can keep one handy on every floor of the house and in the garage. It isn't a fancy calculator, but it adds, subtracts, divides and multiplies faster than I can do it in my head. I'm sure it has some additional functions that I'm not using, but not many. Anyway, the price is right!

Customer Rating: - The Cover is Key
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.
