Review on HP LaserJet Pro CM1415, CP1525 Cyan Toner Cartridge - Compatible with HP 128A, CE321A by Renee Hackbarth

Works great. HP laser printers that use these cartridges warn you before toner is low. Great feature. I also like the pre-printed label and recycling box (free shipping via UPS). The cartridge arrived quickly and works perfectly. Fairly easy to install as all you have to do is flip the container a few times to align the toner, pull the tab, remove the protective bottom cover and slide it in. A bit pricey but the toner lasts a long time.
