Review on Premium Aztech Compatible Toner Cartridge Replacement for HP 58A CF258A 58X CF258X - Black 2-Pack for HP Pro M404/M428 Series Printers by Jamal Yang

This is a much cheaper alternative to the official HP cartridges. However, they are extremely overpriced because they put a chip in the printer so you can only use their ink. However, these Aztechs fix that because you can just replace the chip and then use much cheaper ink! HP sells them for $100 for one and Aztech for $80 for two! That's a $100 and $40 difference in unit price! You will save so much money to keep buying them and they work great. I had no problems installing the chip and it's very easy and no problems with the ink itself, they print great! 10/10 recommend!
