I was skeptical because I have already bought cartridges from other vendors, which unfortunately contrary to their promises were not compatible or without reset the chips were not working.
These cartridges really has it all works as it is in the article description!
Information can be printed with these cartridges from me how long and often are not even possible ... wait and see.
