This product works just like the an OEM replacement at a fraction of the cost. I always order my toner cartridge replacement from Shopper+. It arrives within a few days, fits in the printer perfectly, and provides great quality printing. I have been shopping on this site for years and have never been disappointed. I would recommend Shopper+ and this product hands down to anyone who is needing replacement of their ink and/or toner. You just can't go wrong!

Along time ago, I had a Lexmark printer that required small cartridges which had to be replaced at $50.00 or more each. My Cannon Printer using the 137 Black toner lasts for months of moderate use or for many weeks of heavy use such as printing a book of 40 pages per copy. This is a significant saving.

This is very good produce.

The Canon price is $140 for one Canon-manufactured product. I got three 123 Canon-compatible cartidges for less than $50. That's a saving of over $90.

It's a reliable compatible. Once in a while it might have a manufactuer defective one but customer service always rectify it.

Repeated customer. It's a very reliable product. Occasionally may came across a defective one but customer service dealt with it professional and will either replace or refund accordingly.
