Review on Cool Toner Compatible Cartridge Replacement Computer Accessories & Peripherals by Carlos Phillips

It didn't work. The ink was unsuitable for the printer, left streaks and was completely unusable. I had to throw them away and quickly order another brand. Another brand worked but didn't make it beyond 500 pages. I couldn't take it and ran to Staples to buy the original from HP. I understand the lower quality for the price but all the 3rd party ones seem even more of a scam than expensive HP. They sent me a new set of toners. The problem is when I went to change the HP originals I found that the chips were now filled with epoxy and couldn't be moved. Not sure if they are good or not, my guess is that the last one was just a bad batch. I need to order another set of chips to try them. It will be another 3 months before I see if they work. HP overcharges for ink and won't let third parties compete, it's time to look for a new manufacturer. HP is just annoying when the ink costs more than the printer.
