Moustache is one of the only ink cartridges that my finicky Epson Workforce 840 printer will accept without some sort of issue. The money saved is incredible - couldn't be happier that I found the Moustache brand, sadly 5 years after I bought the above printer. All the money I've wasted..............

Fast shipping and works as advertised! I initially got the "Ink not recognized" error on my printer, but several On/Off attempts seemed to do the trick. There is no longer any errors as of yet. I've done several printing "tests" and not surprisingly, there is absolutely no difference from this ink to the OEM ink. I'm actually kicking myself for not doing my research prior, because I've been spending close to $40 for the black ink alone for the OEM version for many years. I only came across this site because Bestbuy was sold out of this OEM ink, and a simple google search gave me this site. I am a firm believer now that this is excellent quality ink at a fraction of the OEM price. Also this is a Canadian business which I will 100% support! :D

Excellent product! Long lasting cartridges!

Keeps on ticking.

Hasn't failed yet.

Been using these cartridges for years. Work very good.
