Review on 🖨️ Speedy Toner Compatible Toner Cartridges: Lexmark C540N CMYK - Replacement (4 Pack) by Matthew Blustein

The price seemed great compared to Lexmark. I bought 4 packs and should have received 1 black, 1 yellow, 1 cyan and 1 magenta. When I wanted to change the cyan cartridge, there was a yellow cartridge in the cyan box. So I had to buy a cyan cartridge. I put the yellow one aside until I needed it. When I finally needed it, my printer didn't recognize the new yellow cartridge. When I needed the yellow cartridge, the 30-day return period had expired. Now I have to throw away the replacement yellow cartridge that my printer doesn't recognize. It's not that much of a deal. If you can get your printer to recognize the new cartridges, they will work fine. BUT. I wasn't so lucky and now that I've read the other reviews it looks like this is a common problem.
