Premium Combo Ink Refill Kit for Canon PG-40/CL-41, PG-50/CL-51 Cartridges

First time that I didn't buy new ink cartridge. It turned out to be a very easy process to refill my old cartridge. Pull back the label to expose the indentations where you should drill. Drill a little hole, use the syringe to fill up the cartridge, put the label over the hole.It's printing nicely. Even though the computer thinks it's out of ink. On my Canon I just have to hold down the reset button for three sec, once after putting the refilled cartridge back in. Funny thing - I also bought some 're-manufactured' ink cartridges at the same time. Now that I know the process for refilling the ink, I peeled back the label on the re-manufactured unit. No surprise. The exact same hole was drilled there, and they hadn't covered the hole with anything except the label. So you might was well do it yourself. I also found out that the printer doesn't actually sense the amount of ink in a brand new cartridge. I just counts the number of pages that you print. That's why you can usually just keep on printing after the computer tells you that the ink has run out. It's all a big scam.

Will never ever ever buy a new ink cartridge again! Was able to refill mine 3 times with this package. The first fill I did have to do several cleanings and deep cleanings but it did eventually print properly ( I had not used the ink cartridges in about 8 months though). The second and third fills I just had to do one or two regular cleanings before it printed properly. Colors were perfect and it was so easy to do! It did not come with instructions, but there were plenty of YouTube videos to show how it's done. It did however come with instructions. The cartridges I had were refills I had gotten cheap off of the Internet so I didnt have to drill anything, so I can't speak from experience on that part. Saved myself probably close to $180! Will be ordering again soon!

This printer hasn't been plugged in for over five years. I didn't know if it would work or not. I bought this ink to fill up the cartridges p30 and p31. They were really plugged up, but I was able to get most of the nozzles working. I still have one nozzle that is plugged. the ink is great and instructions on website are clear. I do wish I would have bought double amount of black since that's what I usually print with.

The kit works. I did one refill so far and there's enough ink left for at least 3 or more refills for color and probably one or more for black. Not perfect, as the heads are not new, of course, but usable. As the instructions say, several test pages need to be run before the ink is uniform and the print quality improves. Of course, much cheaper than new cartridges.

The quality is good, easy to fill the cartridge, good packaging and content quality, it will allow filing both black and color cartridge for my canon printer three times and i just paid $8. If i bought a new cartridges this will cost $52.

Worked fine to refill cartridges

Very good quality
