Review on Aztech Premium Replacement Toner Cartridge Set for HP 26X CF226X 26A CF226A Pro M402n M402dw M402dn Pro MFP M426fdw M426fdn M426dw Printer (4-Pack, Black) by Dan Tsourvakas

I bought these for my HP. My office has a moderate print volume, about 100 pages per day on an HP and the rest on a larger central machine. The print quality is excellent and fits perfectly on all sizes of Avery shipping labels. No problems with envelopes or letterhead. I was really on the fence about burning enough fakes on Amazon but this is a really good deal.
