The product was cheaper than sold anywhere else, plus, the package arrived rather quickly. Since I last purchased Canon printer cartridges, prices had spiralled up. So, this time I bought bulk of 10 B&W and 10 Colour.
THe quality is great, no question about it. Installation of the cartridge is very easy. My only gripe with it is the cost (no much saving even if it's a twin pack) as I am not sure how long it will last. The ink cartridge looks really small so I am sure I will soon be back here to purchase more. I guess I am ultimately paying for the convenience of portability.
Other than cost, this is a great original product that is very easy to instal and works great.
