Query: Excellent buy

I was tired of paying $80 for a new laser cartridge for my HP 1200 laser printer, so I would try this one for $19. There were only five reviews at the time but they averaged 5 stars. The delivery was fast, the packaging could not have been better and it functioned perfectly from the first printed page. It has been several weeks now and it is still printing perfectly. What more could you ask for? A REAL DEAL!!
