Received 2 units. Inserted first one and it would not seat securely (not click in). Tried the 2nd and it clicked in properly but I got the message that it was not original Canon cartridge. I removed and reinserted 4 times before it would work. Done 20 pages now and quality good. Will reserve final judgement after I see how many pages I get. I called about first cartridge but too much hassle proving the problem, and so I just discarded it. I have ordered more so I can check them out further and will review in a few weeks when I have done 200 pages

Cartridge tends to clot printer head if left unused for more than 2 weeks. Otherwise, comparable to the Canon product.
