You can get Epson "compatible inks for around 1/3 rd the price of genuines. Probems? Yes, they will clog if not used regularly- once or twice a week at least. The colurs are not as vibrant as genuine Epsons- not a good choice if you want faithful photgraphic quality reproduction. Otherwise perfectly good.Here's a tip- IF you use compatible cartridges, don't tell Epson service if something goes wrong under warranty- just put back the originals otherwise they will say you have invalidated the warranty- read the small print!
