Amstech Compatible Toner Replacement for HP 90A CE390A Black Toner works with HP LaserJet Enterprise M4555 MFP 600 M601 M602 M603 Printer Ink(2-Pack)

have used two cartridges so far. I installed the second one yesterday and the printer said it was empty. Keep asking for new things. Not excited...HP M4555 Printer.

I purchased this in August and in October the magenta started bleeding from the toner. Each printed page is completely covered in magenta.

I just installed a black cartridge in my printer, but it left traces of black toner on my printouts. Very disappointed with the quality.

Compared to well-known brands, these cartridges are very economical! I was able to purchase 3 products from this brand at brand price. OK!

I bought two. The first one was okay. The second is damaged (black lines appear on the page). Unfortunately, by the time I used the second product, 30 days had passed and I could no longer return it.
