Review on E-Z Ink (TM) Compatible Gray Ink Cartridge Replacement for Canon CLI-271XL CLI 271 XL -Compatible with PIXMA TS9020 TS8020 MG7720 Printer Tray - 6 Pack by Tiffany Pine

This is my fourth time buying this ink for my Canon Pixma printer. I got the color set and just bought this one because the gray is not included in the color set for some reason. I'm a PhD student and I also teach young children: so I print tons of materials for school and work! This ink lasts a long time (in fact, much longer than my printer indicates: I keep using it even after the printer starts flashing the warning light). I don't use my printer to print photos - I use an app that sends them for professional printing. So I can't comment on how good the ink is for home photography. But for common materials like worksheets, drawings, charts, etc., this ink is great!
