Not sure of the longevity. I have had this cartridge for less than a month, but the print quality is what I was missing from the last companys cartridge replacement. Sharp and dark, not light and lacking contrast. I will chime in about longevity in a month or so, but this is probably my go to cartridge replacement for my Canon MF 229 dw laser.

Fits in printer perfectly and runs like the OEM cartridge. Print clarity is good. Why pay the cost for OEM when you can get this at a lower price? Also like that it is a 2 pack.

I am always leery of using 3rd party toners once the OEM toner runs out.

There is nothing that I dislike here.

This toner is working ok in my printer, I did not get any errors about it not being OEM, which is always a concern for me. The print quality seems good, Ive been using for about a month with moderate use (about 100 sheets) and I have not noticed any deterioration of quality.

The 137 Toner was a perfect replacement cartridge that fit my Canon MF227dw with no issues. The printer quality was excellent. This is a great value, as you get two replacement toner cartridges for less than the price of a single Canon cartridge. Rated 5-stars.

The Aolibe 137 Toner Cartridge was a great purchase. We use a lot of toner in our office and found this to be a great deal especially for the high quality of the product.

I ordered these replacement cartridges for my Canon MF247dw printer. The two cartridges come in one box, each wrapped in a thin plastic sealed bag. However, one of bags had a long cut in it.

Long lasting.

The product is worth the price, I am very pleased
