We were looking for a replacement ribbon for our office adding machine, as ours was running out. We were replacing a original Monroe ribbon. These replacement work perfectly. We've gone through three or four of them so far and all have worked seamlessly!

As described. No issues.

I used to get another brand that I really liked; however, Amazon seems to no longer carry that brand. I went through a couple of others that didn't have the same quality and I came across this one. In the past month I have used two and the ink quality is fantastic. It takes me about four rolls of paper before I have to change a cartridge and that's good because I am on my calculator for 10 hours a day 5 days a week. Hopefully Amazon keeps these in stock because this will now be my go-to brand.

Great for the money but made cheap. Ribbons seems to have lack of ink in it, the reels are easily broken off. I drop one and the reels have broken off, but still able to use it
