    This is the 2nd time I've ordered refills from CompAndSave.com. In my opinion their refill cartridge is just as good as buying a new cartridge - and a lot less expensive. I was cautious at first but I haven't had any problems since using their refills for my HP Inkjet printer. They're product is a reliable substitute.
