Casio Inc. HR-100TM Business Calculator

5 years later and this thing is still going strong! Had to replace the ink tabs ONCE in 5 years- I use this thing DAILY and always have it set to print. Despite the battery issue, I’m giving it 5 stars. Would definitely buy again, but frankly that might not be necessary for several more years!!Purchased this calculator to replace my old one, which I had for about 25 years. The ONLY reason I had to do that is because the old one (which was a Texas Instrument) digital screen was no longer working so the numbers were disjointed and I could no longer read the display. So I scrolled through hundreds of reviews and questions to find the right one and finally settled on this one. So far it has worked beautifully. The printout is clear, the display is clear, everything works BEAUTIFULLY to it totally fit my needs. The only reason I gave it 4 stars instead of 5 is because it sucks when it is on battery power. My old calculator ran off of batteries (it had an AC adapter but I never used it). The batteries in that old calculator would last YEARS- LITERAL YEARS. And it didn't matter what brand- Energizer, Duracell, storebrand, you name it. Any standard AA batteries lasted a MINIMUM of 5 years in that old calculator. So that was the main reason I wanted this Casio was so that I did not have to have it tied to an AC cord indefinitely. Yeah...well that is not working out so well. I put batteries in it and it worked on them for about 2 weeks....I went through about 4 sets of batteries in about two months until I finally decided to leave it plugged in all of the time. But there was a time when not being able to run this off of battery power would have been cause for me to return it. So if you are planning to use this PRIMARILY on battery power- find a different calculator. If you don't mind leaving it plugged in all of the time- YES, buy it.

Clear, well made, capable calculator. I used my late Dad's 1960 Texas Instruments AC/DC calculator until it refused to "take" or advance the paper roll. I might add that in 1960 a simple calculator was enormously expensive- - after almost 60 years of service, I figured it was time for a new one. I read some of the reviews of this unit. and just shake my head at some of the negatives. Everything about this calculator is just fine. For myself and my needs, it fulfills every last requirement -- and yes, I have utterly no idea what 90% of the functions do. . .:)! And, I don't need to. Like most folks I use the unit to balance a checkbook, add up some tax deductions, and do a "percent" here-and-there when trying to price compare things I'm interested in buying. I bought some additional paper rolls, and some ink cartridges (the Texas Instruments calculator used the "chemical reactive" paper, which was fine, but did not print nearly as dark or clear as this unit). Everything ran me less than $40! And people complain? Buy it! It'll do what you need it to do. End of story.

This calculator is excellent for ordinary math tasks.You do not have to install or seat the inker--it comes installed--so please disregard the first 3 star review that was obviously based on an earlier version.It's extremely easy to set up and operate: just remove it from the box, insert the tape-roller holders, place the tape in it, push the edge of the tape through the slat in the rear of the machine, connect the plug to the machine and to an electrical outlet or use it with batteries, push the start button on the calculator, and its ready to perform numerous functions--very easily.All subtractions are printed in red ink, everything else is in black. I did not read the manual because I knew how to do all the tasks I needed to perform, having had a similar Casio machine in the past. But it shouldn't take but a few minutes to figure out how to use the functions by trying each one alone or in conjunction with some of the other functions. It's well worth the $ 20.00 I paid for a new one. It also has a 1 year warranty. You can COUNT on it.

It works well and has all the requisite buttons and functions. The thing that keeps it from getting a five star review is the "C" and "CA" buttons. The red "C" button, unlike any other calculator like this I've ever used in my life, does not actually clear the totals. You have to use the "CA" button for that. I suppose it makes sense to some people, but it took me a while to get used to the fact that the brightest button on the calculator doesn't actually clear things like I would expect. Aside from that, it's a good calculator
