These did a great job and were a lot cheaper than the name brand replacements.

These are the cheapest ribbons you will. Half of the ones I ordered are dry and wont lay down print at all. Absolute junk ! Save your money and buy the more expensive one for better results

Tried it. At least 3 of the 12 failed prematurely. Got little black stains consistently in some cases as the ribbon stuck and could not be wound using the thumb shaft. Its hit or miss and may hit for a big then miss. Frustrating. Down to last three. Ordered originals today
