Ordered this a few times. Always come back for more. Great product no problems. Great price.

Not issues, good length of life from the ink

I've used these for years and never had a problem with my printer heads or or printed product. NOTE: The one thing that sometimes happens is more my own fault with mishandling and ink spillage so BE GENTLE when unpackaging and loading, and WEAR NITRILE GLOVES.!! As with all printing ink, DON'T drop the cartridge on the carpet.!!

Good Product highly recommended

It's basic inkjet ink for an excellent price. I'm not printing anything fancy so that's what I shopped for and that's what I got. I don't know how these companies got to stomp all over the ridiculous prices the printer makers charge and frankly, I don't care too much. I'm just glad it happened. Thanks for existing!

This is my first time buying from this vendor. I usually get my ink straight from Canon but because of the positive reviews I thought I'd give this ink a try, and I'm glad that I did. As you can see from the pictures, the ink cartridges are very well made and appear to be high yield, so I should be able to get around 600 pages on these. My original Canon cartridges are on the left, and the OSIR cartridges are on the right.Canons cartridges are black so you can't see how much ink is left, but these OSIR cartridges come in clear cartridges, which is really nice because you can easily see when it’s running low on ink. Each cartridge is also separately wrapped. These cartridges come with the Canon chip on them, and the printer has no idea that it's not real Canon ink. Printing a test picture the ink looked every bit as good as the Canon ink. I will be using this ink from now on.

They work fine with my Canon Pixma TR8500 Series printer for several years now. So Canon hasn't disabled compatibility for a while now. I have no idea of the longevity in comparison to other manufacturers, but overall none of these cartridges last as long as they used to. It also depends on your printing levels, I print a few sheets a month (Amazon return labels). I will advise to do a cleaning (via printer settings) once a month to prevent clogging. This wastes ink but prevents functional loss of an entire cartridge and possibly clogging the printer as well, which is far more costly.

UPDATE: Just updated the rating to 5 stars based solely on OSIR's after-sales support. They have been relentlessly committed to resolving my previous issues with their product. Admittedly, out of frustration I just ignored their early attempts but I'm please to say they persisted, which is why the change in rating. At this point I am quite willing to try their product again since I know they will stand behind it one way or the other.==========================================Bought these cartridges for my Canon TS8320 in July just to have them on hand. Like most things in my business, I like to have backups or replacements readily available to eliminate down time.Well, it’s now October and one of my original cartridges needed replacing. I popped in the Osir cartridge and my printer won’t recognize it no matter what ‘tricks’ I try. Of course, the 30-day return window is long gone so now I’m stuck with cartridges I can’t use. With all of the exemplary reviews I didn’t think there would be an issue. Plus, my printer is included in the list of compatible printers. Needless to say I won’t be ordering Osir cartridges again.
