I usually order this HP Laserjet 15X cartridge from Costco, but when I saw a cheaper price on Revain.com I ordered this one. However, it was a defective cartridge that left streaks all over the paper, even after I distributed the toner according to the product instructions, cleaned the printer, etc. This is not the supplier's fault. I believe that any cartridge can be defective. It was written on the packaging that it was an original cartridge, not a reman cartridge. However, it behaved more like a remanufactured cartridge. I ordered a replacement cartridge from Costco and the replacement works great, so it's not the printer. Trying to save $15-$20 (cost difference between Costco and Revain) I lost $70 because the cartridge had to be thrown away. Lesson learned.
