Review on Aztech Compatible Cartridge Laserjet M401Dne by Ryan Lawson

I got this a while ago and was waiting for it to finish. The first goes well with a good print, but until I used up to 30% I noticed that part of the print gets lighter and lighter until there is no empty part left, even if I take it out to shake it (I know it may not have any values), it usually prints a few pages and starts again. I had to change, although it is written that 30% remained. With the second, it's even worth starting at 40% rest.
