We only provide extra quality ink jet inks, complying with all the specifications of the emulsions involved in the various inks for the various inkjet printers. Yes, we will replace ink cartridges that are defective or damaged or refund you at our discretion. The statistically most accurate answer is between 5 and 10 times that is for a printer cartridge which contains its own printhead. The same applies to cartridges where the printhead is in the printer and the inkjet cartridges are the ink tanks. A clean printhead is key to a good printout.
Field reports indicate good results.
To be sure, some ink tanks rely on internal sponges to store the ink and sponges can dry if left unused. There are ways for recovering from a dry sponge and the process is not complicated. No, all cartridges are refillable. This is the basis of our business. You can refill the cartridges you already own, or cartridges you purchase from us online with the same quality ink again and again.
