"Remanufactured Inkjet "
 

Remanufactured Ink Combo for Epson Stylus Photo R200/ R300/ R300M/ R320/ RX500/ RX600 Printers ( T048120, T048220, T048320, T048420, T048520, T048620 three each - Total 18 Cartridges )

I was thinking of trying this, anyone used 'ink' like this before?

Other than the original Epson cartridges that came with the printer, remanufactured is all I've ever used in my R300 and had no problems. I think I've used over 100 cartridges. I once had some plugged nozzles, but I think that had more to do with not using the printer for several months. Running a few cleaning cycles fixed it.
