Review on Aztech Compatible Cartridge Laserjet M401Dne by Daniel Roe

I bought 2 cartridges but while 1 worked fine the 2nd printed black pages. I'm pretty sure the cartridge was damaged as there was loose plastic inside. No damage to the box. REVISED: A cartridge that initially worked later failed, long before the toner ran out. It started making noises like the roller wasn't spinning properly and then the paper jammed. I replaced the toner to make sure it was the problem. Do not buy.
