I have ordered the 12 item multipack to use it for my SX200 reluctantly, at the beginning, because of the, too good to be true, price.
The cartridges arrived very soon and in good packaging. I had no problem installing them and the printer had no problem recognizing them. I didn't even get a "not a genuine cartridge" message!
When it comes to printing quality, they perform very well. If you want to print text and pictures you will have absolutely no problem at all. Their performance is immaculate. If you care more about printing on a photographic paper, then you will not have the same quality as the ink designated for that job. But I think you all expect that.
When you work with epson printers it is important to open the cartridge from the packaging and getting it ready for installation first, THEN exposing the printer head and opening the cover to replace the cartridge (and do it fast) or else you will probably have clogs. This applies when you use these cartridges as well. I write this because I am sure that many of the complains I read here are caused by clogs.
