I have these cartridges ordered from Uwe and Sabine Bublat in Juni.2012 through Amazon. I really print a lot and my balance after about 5 months: Tol, I'm really excited about these cheap cartridges and had hardly noticed a Qualitätsnterschied to the original. Only once did not recognize a black cartridge from the printer. I picked up the phone and had men Uwe Publat quickly and efficiently in person at the other end, who explained to me how to solve this problem. And it worked. My Opinion: Great price and great service. Order!
