I was very impressed with the prompt customer support for a simple question regarding the key for the ink cube. The rep was very professional and provide clear instructions for results in 2 minutes.I will definitely purchase more color cubes for my Xerox 8580 in the future and share the resource at work for the multiple Xerox printers we have for our college labs.

This is the second time buying this product and it works great and definitely at a much better price than anyone else

They fit my printer at a decent proce

A bit difficult to use.

We tried the little "key" to help us get the ink into the printer, but now we can't get it out.Looks like I have some work to do, I hope I can be able to use the printer again.

They fit well with simple instructions for the bypass key. Great email follow up to the sale as well. I will order again.

no problems w/order

2nd time I have ordered this product and it works without issue.
