It was great for a few months but then it stopped feeding paper.  I changed the paper types and did everything I could think of but it wouldn't work.  I found online that I wasn't alone with this problem.  I contacted Canon and they were great about it.   I gave the serial number to them and they offered a warranty exchange.  They sent me a new one and I just had to drop the old one off at UPS with prepaid shipping.  It is working fine again, which if it keeps working I will be a satisfied customer.  However, I suspect that I may have this problema gain in the future.  It also eats a bit...
