The Moustache brand is a decent alternative product for any printing needs. This is my 3rd order for these particular cartridges, and everything was smooth as glass as usual. I popped them in the printer, got no fuss from the machine, and was up and running in minutes. The added convenience of being able to order these online, and then having Shopper Plus or 123 Ink get them to my door in 3 days or less makes me a repeat customer!

I THOUGHT IT QITE AMAZING HOW WELL THE CARTRIDGES WORKED,IN THE BEGINNING. THEN MY HP 6520 STOPPED WORKING COMPLETELY BECAUSE THE BLACK CARTRIDGE WAS COMPLETLY BLOCKED. SIMPLY COULD NOT FIX IT AND HAD TO DISCARD THE PRINTER. THAT SAME WEEK MY BROTHER MFC 495 STOPPED PRINTIG AND NEEDED AN EXTENSIVE CLEANING. TOOK SEVERAL PASSES TO GET IT WORKING AGAIN. SHORTLY THEREAFTER THE CARTRIDGE CYAN LEAKED AND HAD TO BE REPLACED. WE HAVE 5 PRINTERS ,ARE COMPUTER LITERATE AND WILL AVOID 123 INK AT ALL COST IN THE FUTURE. ALFRED EICHNER

I also purchased HP XL magenta, cyan and yellow cartridges and the problem is the same as for the blk cartridge.

I bought this HP 564XL BLK cartridge but it does not print the document. Attached file shows what is printed.

Woks extremely well like the manufacturers original inks.

These inks work very well just like the ones from HP
