I have used Inkredible numerous times and have never been let down. The product has never failed me nor has it ever had any advert effects on my printers. The package has always been delivered in good condition and in the next days mail.\nFast efficient service. Quality products at down to earth, affordable prices. Why wouldn't I recommend it?
