I have been ordering replacement ink cartridges for almost 4 years for two different printers. One is an HP and the other is an Epson. I have never had a problem with the remanufactured cartridges and in fact do not really notice that they have less capacity. In other words I seem to get the same number of pages as when I used the OEM cartridges. The prices that LD products offers are extremely reasonable especially when buying in bulk. For my HP printer which I use more often I buy a bulk box as the savings are quite substantial. I do not notice any problems with the shelf life even if the expiration date is passed. I just keep the cartridge in and my printer runs just fine. I do notice that my Epsom printer seems to be an ink hog but frankly it was the same way when I was using OEM cartridges so I think it is just a function of the inefficiency of the Epson printer. I had similar problems with another Epson printer so I think it is a function of using a printer that has a higher efficiency rating for ink usage and my HP printers typically do not give me problems.
I will continue to use LD products for all my printing needs and always refer my friends to their site for the great deals and great customer service.
