V4INK 2PK Compatible Toner Cartridge Replacement for Canon 104 CRG-104 FX-9 FX-10 Toner Cartridge Ink for use in Canon Imageclass D420 D450 D480 MF4150 MF4350D MF4270 MF4370DN MF4380DN Printer

So much less expensive than other options. Always worked great.

Good print quality. I had to switch from another manufacturer because of toner defects.

Everything to like. Worked as well as the original Canon printer Toner, just much less expensive.

After about 6 toners over 8 years I did finally notice some lower print quality on the last cartridge. The price point is certainly a good deal if you don't have any print issues. My issue was a slight streak that started after inserting and using a new toner cartridge (was working fine right before the exchange).

The cartridges come very well packaged inside custom bubble puuches. The protective strip and two tabs that must be removed before installing are color coded and the instructions are simple and clear.I always look for good deals and two toner cartridges for less than half the price of a Canon cartridge wouldn't be a good deal if they didn't print well but these work great. Alsok I don't print a lot but the fact that the toner still prints well after sitting for weeks between prints is a huge plus for me.I have a very old Canon MF4150 that still works great and I would recommend these to anyone with a similar model..

Works great thus far - have only printed 10-20 pages in the first weeks

These v4Ink toner cartridges seem to be of high quality. They're packed well (two to a box). And they come with surprisingly robust instructions and a large sticker to remind you that you have a 2-year warranty. After you open the bag with the cartridge, you must remember to pull the two orange tabs at the ends of the cartridge off. These tabs appear to lock the cartridge rollers in place during shipping and storage. You must also pull out the white plastic strip that opens the toner tank, as with every toner cartridge I've ever used. I slipped the prepared toner cartridge into my printer and the red "replace toner" light didn't turn off, so I printed a 50-page cookbook anyway. After that, the light was off. Something with the way the printer works, I guess. The 50-page cookbook came out fine. All-black pages looked a bit splotchy if you look carefully and the toner certainly smells different as the printer is printing. Something to do with the fusing process I'd guess. The text and photos in the cookbook came out fine, so I took one star off for the splotchy black fill but otherwise, I'm very happy. These cartridges cost less than one seventh that of the original Canon 104 cartridges, so I'll happily tolerate the slightly poorer quality of the solid black areas. I'll also learn to ignore the odd smell. The v4Ink warranty sticker went on the side of the printer.

Our old printer needed a new cartridge, and Amazon delivered the correcct one at a cheaper price than we have paid ever before. Perfect!
