I immediately put the cartridges in the printer. I started typing but then there was a problem. The color cartridge was fine, but my printer could not "read" the black cartridge. I returned to Revain to request a replacement. The seller responded very quickly and I received a replacement very quickly. I put it on my car and had no problems. Excellent value for money in my opinion. I gave 4 stars because the first black cartridge was defective. Would have given 5 stars if the black worked the first time.
