Black Ink Refill Kit for Canon PG210 PG-30 PG-37 PG-40 PG-50 PG-510 PG-810 PG-830 Cartridges

I can never get anything fiddly done while my kids are awake, so imagine my surprise when I was able to successfully refill not one, but TWO ink cartridges while tending to my kids! I refilled the just-emptied cartridge from my printer and an older one that had been dead for a long time. The dead one came back to life after I put a little Windex in the bottom of a plastic container and let the print head soak in it for about 10 minutes. The "only mostly dead" cartridge just needed a couple of head cleaning cycles to get roaring back into life.The instructions were very clear. I had expected that for so low a price I'd get instructions written in Engrish, but I was pleasantly surprised. The squeeze bottle that the ink comes in is very cleverly designed to be put underneath the cartridge to hold it in the proper position while the ink soaks in. The drill tool is also very clever and I will hang onto it so that I can use it for crafts. My only disappointment is that there are only 1-2 refills in each kit, but I would gladly buy this kit again (and probably will!) I can't wait to try the color one next, as soon as my current color cartridge runs out of ink!

I was sick and tired of paying so much money for the canon cartridges, so I decided to give this a shot. I wish I had discovered this sooner. It would have saved me lots of money.The instructions were clear and very easy to follow. Perhaps the worst thing about this system is the little finger drill that is provided to access the inside of the cartridge you intend to refill. I was not making any progress with the finger drill so I quickly abandoned that thought and just grabbed my electric drill with the same size drill bit and got through in no time.While refilling the cartridge, the ink would occasionally bubble up through the hole and you have to be careful not to keep squeezing or you'll make a bigger mess. After filling up the cartridge with about half the bottle (each kit will supposedly refill 2 cartridges) I wiped all of the ink off that had bubbled over, let it sit for 20 minutes or so, and then tried it out. It worked fine.I don't think the quality is as good as the authentic canon cartridges, but I am using my printer solely for the purpose of printing large amounts of documents where I am not concerned with a perfect presentation. If I can read what I'm printing, it's good enough for me. And that's exactly what this system does. I have yet to try and print something in high quality, but for my purposes, it has definitely been worth the money and I intend to purchase it again when the need arises.

This is a great product for refilling those pricey inkjet cartridges. I've found the best way to refill my Canon Pixma inkjet cartridges is by poking a small hole in the edge of the cartridge with a hot paperclip. (Unbend one of the ends and hold it over a flame till it glows cherry red. Do this while holding the paperclip with a pair of pliers.) Then slowly refill the cartridge till it's full; it should take you 2 minutes to refill the cartridge. Let it rest, hole side up for 20 minutes. Then seal the hole with glue from a hot glue gun. This will be a messy process so do it in a stainless sink, or possibly outdoors. Wear rubber gloves too. It's a bit messy, but you can refill many cartridges this way for less than the price of a single cartridge.

I read the instructions and tried to use it but it was just too messy and maybe my ink cartridge was already dried out. The ink did not go inside of the cartridge like it was suppose to so I just ended up throwing it out! Good luck to all of the other DIY-ers!

I was looking for an inexpensive alternative to buying new printer ink cartridges. This is the first Refill Kit I had ever bought. The quality of the ink was good, but it ran out so quickly, and being the novice I was, I didn't know they had been very stingy with the quantity of ink they sent. I never bought this again. Instead I found another deal and another supplier where they sent a large bottle of at least 50 times more ink for the same price! I give this product a failing grade, because of the ridiculously small quantity.

The seller was terrific; I got the product very soon after ordering, professionally packaged for shipping, the whole 9 yards.The product itself is easy to use (directions are included), but the ink is not the best quality. If you have a 'before refill' and an 'after refill' printout you can clearly see how the refill ink is lighter colored and more prone to streaking. If you intend to just print out single-use things (directions, funnies from the web, etc) it's a great way to save money. I wouldn't use the refill ink for things like family photos, though.

This was my first refill kit I have ever bought.I refilled the ink within 5minutes and had the printer back up and functioning perfectly!The printer still says "black ink low", but I don't pay attention to it and it does not effect the printing as I use it as our network printer at home.A big plus also is I still have 1/2 the bottle left for another refill!This definitely beats the $30 retail price of a whole new cartridge!

I have always heard good and bad about the ink refills. I read the reviews on this one and decided to try it. One of the " problems" I had read on other reviews that the little drill like tool they send you to make the hole was difficult to use. I solved that problem by heating it with a ciggarette lighter and it made the hole perfect. After that it was easy to fill with ink. And it has worked fine ever since. It prints just like it did with the original cartridge--nice and crisp. The light does show for low ink but I know that it's not. There was enough ink in the bottle to totally fill it up one time and there is enough left over to fill it about 2/3s full the next time. I am very pleased and will definately order the colored ink when I need it and also the black again.
