This is the last week for the HP Ink Challenge. For 5 weeks now I've tried out HP ink and refill ink to see how they compare. For me, installing both inks was pretty straight forward. I printed about the same amount of prints from each printer, maybe a little more with the HP ink, and now every time I print with the refill printer I get a "low ink" warning. HP ink is definitely lasting longer and has been high quality from the beginning. The refill ink is good, but shows streaking and less vibrant colors. I'm not sure I would notice it as much without a side by side comparison. If I had something important I needed to print I would have definitely noticed. HP ink is more reliable than the refill ink and I guess that is why it's more expensive. :) Sometimes you really get what you pay for.
I printed for the last time the same 5 documents to see how they compare to week 1. The HP prints look exactly the same to me as the first prints. I didn't see much difference with the refill ink prints either. Although the refill prints did start out with streaking and weak browns. Since the only reason I buy color ink is to print pictures I would definitely buy HP ink instead of the cheaper refill. The refill ink isn't that cheap! Thanks to HP for a fun challenge!
I received two free HP Deskjet 3510 printers and supplies as well as a gift card to purchase refilled cartridges from HP in order to participate in the Ink Challenge. All opinions and views expressed are my own.
