I have just bought a CanonMG5350 and I can't tell you just how disgusted I am in the cartridge size. I have replaced an IP4500 which has served me so well over the last 3 or so years. The cartridges for the MG5350 are over a third less in capacity to those in the IP4500. I am starting to run out of Cyan ink after printing about a quarter what I could print on the IP4500. The price and size of cartridges has got way out of hand.
