I ordered "guaranteed compatible" cartridges for an Epson 520.
What arrived was not recognized by the printer - obviously an imperfect knockoff.
I sent four EMAILS over the course of three weeks to both Customer Service (laugh here), and the RMA people. There was not ONE response!
I'm out $40 - could have been worse.
Next time, I'll check with consumer complaints first before trying a new company.
The printer is working fine now that GENUINE Epson cartridges are in place.
