I purchased this system when I got my new printer on Feb 5, 2009. It is now March 25, 2009. I've been using this for about 6 weeks now. It took a bit of work to get it installed correctly because the ink ribbon must be in exactly the right place, and it has to move smoothly and stay out of the way. It took some tape in strategic places to make it work right, but now I couldn't be happier. The quality of the ink is great! The colors are just as vibrant as the Epson cartridges. You'll notice that the print window will show ink going down, but at some point it resets itself and they show full again. I had to force the machine to recognize the black once by pulling it out and putting it back in. I use a lot of color, and I would have already had to replace all 4 of the colors at least once. This system is still mostly full. It has already saved me money. The price has gone up since I bought it, but it's still a good deal, considering the cost of Epson cartridges.
