Octopus 6x 100ml PureInk refill ink compatible for Canon PGI-580, CLI-581 printer cartridges for Canon Pixma TS 8120, TS 8126, TS 8150, TS 8151, TS 8152, TS 9120, TS 9150, TS 9155 (not OEM)

Out of all inks, whether cartridge or refill inks, these have out performed them all. I consider myself fairly fussy when it comes to quality and these exceed my expectations. If these inks resist fading and hold the colours, only time will tell, i will not use anything else. Anyone hesitant about refill inks and using these dont be, you will not be disappointed. Edit update, I failed to mention the foam cap stopper was missing from one bottle thus ink leaking from bottle when laying down in box once opened.

I must admit to being a little bit wary of having to fill my own ink cartridges but it is far easier and cleaner than I imagined in fact I quite enjoy it now

Print performance is indistinguishable from original inks at a fraction of the price. I've not identified suitable independent cartridges but topping up originals is working well so far.

Have not used the product yet. Instructions were hard to read because of tiny print and not clear where [or if] to drill a hole in the cartridge

refilled two different sets of canon 580/581 cartridges for my TS8350, NONE OF THEM WORK PROPERLY AFTER BEING REFILLED WITH THIS INK. was very careful not to touch the chips etc and to carefully fill them, but the yellow ink particularly shows as lines and results in overall poor print quality, I've wasted about £10 worth of photo paper and ran multiple nozzle cleans and even a deep clean wont fix it, even tried refilling multiple different cartridges (that weren't dried out or anything). Apparently there was an issue called "YELLOW JELLO" where some 3rd party yellow inks can react with the original canon ink present in the OEM cartridges and it causes issues - which would explain a lot. Complete 100% unconditional waste of money.
