Review on SCINK 270XL 271XL 270 271 XL Ink Cartridges 4 Sets with Gray - Perfect for Pixma TS9020 TS8020 MG7720 Printers - 24 Pack of High-Quality Ink Cartridges by Kenny Stephens

This product is a small part of the original required ink cartridges. The quality is almost the same. You have to fiddle with flipping the cartridges in order for the sensors to detect them. They are not as viscous as the original inks and great care must be taken not to wash out the color during installation. Cartridges, once installed, last a long time if they are not left in the printer for a long time. I just bought a few extra ones to make up for issues that more than make up for the shortcomings with installation and long term storage. Even if they are sealed in bags and not opened, they will last for quite a while if you shake the karagi slightly from time to time and keep them in a dark and cool place.
