Because of the bad reviews I was suspicious whether the thing would work. Now I have an original cartridge must be replaced (the thick black PGBK) for the 1st time. Agent carpet knife and tweezers I did not find it particularly difficult to replace the chip, but a sure instinct are required. So maybe not the best for everyone. My Pixma accepted the cartridge without difficulty, it reports just now continues that it was empty. As these cartridges are transparent, however it is easily possible to take them out and look up how much is still in there. I like that, because in the original cartridges is often reported long before conclusion that it was empty, and then you can still print another 100 pages with it. This rip-off attempt one is now no longer exposed.
Since the print result on recycled paper but I am not convinced I give only 3 Stars. The cartridge emits more ink than the original, which has said on recycled paper means that the ink easily bleeds into the fibers. I know that you can adjust with my Canon somewhere how much ink it should use, but whether this will work for individual cartridges I do not know. When in doubt, I have to try it when I eventually replaced all the original cartridges.
For people with little money but these replacement cartridges are a good solution, so I can recommend buying.
Worth mentioning were still the fast shipping, and that the instructions in English, and has pictures.
