I bought a set. All can work. But, be careful to unpack it. I wrongly touch something and the Magenta cartridge has leaking and leave strip lines. Other cartridges work perfectly. As it was my fault, I did not claim return.
Yes, I recommend it to other buyers.
The price was great and deliver was early. Used them to replace leaking aftermarket refilled or knock off toner cartridges. Smearing problem solved and working like new again!
