Easy to install. In July 2022, I purchased the 2-pack Economical Box in order to save money. However, when I used up the first cartridge in November 2022 and installed the second unit, I ran into some difficulties. It seems the cartridges have built-in microchips that include a certain expiry date code. Somehow I was able to use the second unit until December when the printer shows that the cartridge ran out of ink. From now on, I will only order one cartridge at a time. Expensive lesson learned!

This laser toner is economical for my pocketbook because it doesn't come with unnecessary packaging. It fits well into my Samsung M2020 laser printer.

Good product for the price

Have purchased several times. Works very well for me in my small home office. And reasonably priced!!
