Query: Beware of "replacement" inkjet cartridges

Buyers beware: this is not the genuine Epson T009201 inkjet cartridge. Don't waste your time with this type of so-called "replacement" cartridges. They will just clog up your Epson printer's printhead with junk ink. I have learned my lesson, and now you have been warned.
