Nothing new here. But it might be new to you. (This was over  a year ago.)

Consumer reports is a credible source. Here is part of what they found:

Third-party printer ink was in the news this spring when the Supreme Court ruled in Impression Products, Inc. v. Lexmark International, Inc. that third-party companies could refill toner cartridges originally sold by a printer manufacturer.

Lexmark had argued that Impression was violating Lexmark patents by refilling and reselling such cartridges. Neither company would comment on the lawsuit. And Lexmark, HP, Epson, and Impression Products did not agree to discuss ink prices with Consumer Reports.

In CR's printers survey, 63 percent of RESPONDENTS who used aftermarket cartridges say they’re just as good as name-brand cartridges, while 36 percent think they’re not up to par.
Our testers have found inconsistencies with third-party cartridges.
Rich Sulin, who leads CR’s printer-testing PROGRAM, says that some samples worked without any problems but that other samples of the same products “set off warning messages from their printer or failed to print a test page.” Additionally, he says, “some aftermarket inks worked initially but quickly clogged printer heads.”

Experience ? ? I would say in my experience shame on you for calling Consumer Reports credible...

What they don’t share with you is that they are PAID affiliates.  Thus, product rating and reviews can directly impact the total revenue Consumer Reports can generate
