Review on HP 128A Toner-Cartridges (CE321A, CE322A, CE323A) in Cyan, Yellow, Magenta - Compatible with HP LaserJet Pro CM1415, CP1525 by Adrian Summers

There are a number of replacement toner cartridges out there, but most of them have questionable ratings. buy the right things. On the plus side: I have a Prime, but I wasn't expecting such fast delivery - the package was supposed to arrive on Sunday, but it was there on Sunday morning, right after I brewed a pot of coffee. Also, I didn't expect (I must have missed the details) a return label for each used cartridge - all I have to do is take it to my local UPS store right away. It was a nice touch.
