Review on 🖨️ GREENSKY 128A Toner Cartridge Replacement Set - CE320A CE321A CE322A CE323A, Compatible with HP Color CP1525n CP1525nw CM1415fn CM1415fnw Printer (4-Pack) by Jonathan Unruh

Good print quality - happy with this part. Unfortunately, the loud high-pitched tone during printer calibration (every 2 hours) interferes with thinking during calibration. The high-pitched tone continues throughout the cycle (about 1-2 minutes). So loud I have to finish my conference call with work. During the elimination process, it appears that only the yellow toner cartridge is making the NOISE. If it hadn't been for that, it would have been a full 5 stars. UPDATE 09/08/2021: I travel a lot so my apologies for the late update. The company contacted me and supplied a replacement set of all the cartridges to make sure there was "noise" and was replaced. This fixed the problem and I will continue to buy toner from them. Excellent customer service.
