Monroe Systems for Business 6120X 12-Digit Business Medium Duty Calculator, Black

I bought the brand not the model. These folks make the industry standard and I’ve used them for over 20 years. They are priced affordability and they get the job done. Period end of story..

Love the way it is easy to use. Very well made machine. I’ve owned many calculators in the past 60 years. This one is my favorite!!

Where do I start? I'm an accountant and have been using adding machines for 30 years. I got this one ten weeks ago. This adding machine doesn't recognize my zero unless I pound on it, it generates incorrect figures, the top piece comes loose after about 20 numbers input, so the paper jams unless I stop in the middle of a column of numbers to push it back in place. Bottom line - I can't trust it, so I'm constantly re-adding my columns and double checking the tape. This is NOT helpful and causes me more work. It worked pretty well for a month, but then started throwing more and more errors.

Nice machine, not as heavy duty as some I have had or at least the key press doesn't feel the same. Functions well. Packaged well. Delivery quick. No complaints.

After going through multiple Canon, Casio and other brand adding machines I have become disgusted with the sticking buttons and malfunctioning printer. So, I finally broke down and bought a Monroe System. So far I have been using this machine in my business for a few months. The quality difference between Monroe and Canon, Casio, etc. is astronomical. When we wear this machine out (much longer than other brands) we will definitely be purchasing another​.

I haven’t had a real 10 key in a while. This machine is business grade. Looks and works excellent. Much more professional than the cheap competitors.

Love this calculator. Keypad is comfortable and responds nicely. I would highly recommend and I don't post reviews!

I bought this calculator because I thought it was going to be a nice, simple, easy load printing ribbon calculator, HOWEVER, every time I've had to install a new ribbon it will not install easily and ends up tearing up the ribbon! I installed a new ribbon today and after many attempts to get it in properly I thought I had it BUT as I was punching in numbers, the ribbon jammed and got stuck in the calculator and wrapped around equipment that cannot be removed. I had to cut the ribbon and tried pulling out the remainder but no luck! Therefore the entire calculator is useless now. I've only had this thing for about 9 months and went through 2 ribbons that wouldn't install easily. I even bought the Monroe brand calculator ribbon and not some knock off. Very aggravating!
