Canon CLI-251XL High-Yield Gray Ink Cartridge (CLI-251G XL) - Compatible with PIXMA Printers - Perfect for Home Office & Photo Printing

fast shipping and great pricesI used the cheaper inks and cleaning up my printer cost me more than the good canon inks would have cost. I will only use these for my canon printer. Highly recommend.fantastic productI had used off-market ink tanks and eventually found that there were more problems with them than using the brand name recommended for my Canon color printer. Despite the increased costs over off-market brands I like the security of knowing that performance is more readily guaranteed with the brand name.good replacement cartridgeValue Packs and Individual Colors to fit you printing needs. Authentic…safe for your printer.Reliable quality & installation fit, but, rather expensive.Although, less expensive brands' ink packages often do not include a grey ink.In that case, this stand alone is a handy fill-in for their shortcoming.Okay, let me break down my star rating here so it makes sense.... this ink is fabulous and as inks go it is a 5 star product. So why only four stars? Two reasons really.... the first and most important is that I just really don't think it lives up to its XL status. There just does not seem to be all that much ink in these tanks to merit such a label. I go through them like they're water. While it is true that I have been known to print many 8.5x11 photos, I still think that something labeled XL should last more than 20 or 30 prints. These often don't. The second is that each tank is a bit ridiculous in its pricing. I mean seriously. At the prices they charge for ink, Canon should be throwing in the printers for free. Its pretty insane.I understand why so many people go for the cheap 3rd party inks. Believe me I've been tempted. I have a hundred dollar month ink habit. Totally ludicrous.One other important point about this ink.... I've been using these particular inks for a couple of years now and I've already described that I do a great deal of printing and have probably gone through 20 gray tanks at this point. I have NEVER had one clog on me. This is impressive. Not that ink tanks should clog, but many of them do. Not these.So there you have it.... Great ink but not so very cost effective and you don't get all that much.BOTTOM LINE: I highly recommend this ink but I understand the need to look for less expensive ink. I will stick with canon ink but it gnaws at me that this one ink tank is 20% of the cost of the printer. Honestly I would love to give it 3 stars because of the cost factor but the ink is just so good I can't bring myself to do it.For some reason the Grey cartridges are hind to find in my area. The appear to be genuine and at an acceptable price.Se acaban muy rápido!Received in a timely manner and performs as expected.Product as advertised, I will buy more when needed.Works well....very pleased.
