Epson printer and Epson ink equals a reliable system.
Size: Standard Capacity, Style: Ink
These Epson Ink cartridges always work. I understand that aftermarket cartridges are cheaper but in the past after using them my printer overtime will fail and ill need to purchase a new printer. I have only used these Epson 822 cartridges in my most recent printer and it has lasted the longest.

Necessary purchase
Size: Standard Capacity, Style: Ink
Our household has two of the same kind of printer that takes this brand and number of ink, and we have had no problems with the ones we've bought. It's just frustrating that the cartridges are SO expensive, and they have to be genuine, the printers won't run remanufactured ink.
