Having already acquired several lots of these compatible, the price-performance ratio is unbeatable. Quality is also the rendezvous. With a printing medium 150/200 sheets / week (display, web pages, various cards), the life thereof is excellent. The batch purchase helps guard against a possible failure due to lack of color cartridge. Recognition by the printer (Epson SX445W) is immediate and managing cartridges by the software is no problem. I recommmandes.
