Octopus 4x 100 ml PureInk Refill Ink, Printer Ink compatible for Canon PG-545 black PG-545XL black CL-546 color CL-546XL color Printer Cartridges, Canon Pixma IP 2850, MG 2450, 2455, 2550 (non OEM)

These bottles area bit deceptive on screen. They're fairly big and depending on the cartridge you should get a good many refills from them. The print quality is fine on standard A4 paper colour or black. I haven't printed anything on photo paper yet, but I expect it will be fine.My instructions were in German, but I copied the relevant details from the page on screen which showed an English translation. they're easy to follow.

Other than the instructions being in German it seems to work fairly well.The amount of ink for the cost is excellent. I've attached a couple of photos to show the unboxing and the steps taken to fill the cartridges. I used a 1.5m drill bit. Don't let the kids get hold of the needles (they are huge). Also, don't use the same syringe and needle - keep them separated per colour (obviously).Please note: The printer does print as I've shown but the printer gets confused continuously showing low ink meaning the print time is a bit longer than expected.

This product is just what we were looking for. We wanted to be able to buy ink for our printer that wouldn't break the bank especially with the amount of printing we needed to do. By buying this kit, we have saved a lot of money and it is not that difficult to do. The first time will be the hardest as you need to make the holes bigger in the cartridges, which we just screwed a screw into the original hole to make it bigger, but from now on we can just refill as the hole is prepared. There are plenty of videos on the internet if you are unsure of how to do it. With the black ink alone, we will get 10 refills so easily saving over £100 for one cartridge!

I assume it will work ok , but I have not used it yet as we are in the process of moving house , so I cannot answer this yet , but as this item is from Amazon I know it will be ok . Thomas

Good stuff. I sealed them back with some tape where I punctured with the needle. Did have to drill a mini hole in the cartridge because the needle wouldn't fit directly.

with my cartridges filled i got very good prints it was very easy to fill them fiil before they are empty

Very pleased easy to use everything included even plastic gloves

It is very good
