After doing a lot of research, I was hopeful that these replacement cartridges from Kingjet would work well while helping keep our ink costs down. HP does a lot of PR to dissuade people from using non-HP products, so I was hesitant at first. I only needed to replace one color at the time but I decided to purchase the bundle (as I knew that the others would run out soon too). The replacement cartridge for the first color we needed worked perfectly, so we set aside the other colors for when we would need them.I have several printers so I didn't use this one as much for a while, but when it was time to replace the large black cartridge, I ran into a problem. As it turns out, a recent firmware update from HP caused the new cartridge not to work. Even though it was a couple months after the initial purchase, I reached out to Kingjet's customer support via Amazon to see if they could help out in any way. I only expected them to help me understand the issue and point me to another product to purchase. Their service team went above and beyond! Not only did they help me to understand the problem (HP's firmware update locked out the ability to use the cartridges I had originally purchased), they offered to refund our original purchase price or send me a full replacement set of cartridges to try (if those didn't work, they said I could again opt for the full refund). Given my satisfaction with the original transaction and desire to find a good company from which to purchase re-manufactured ink, I opted to try their new cartridges (the ones now labeled 'Updated Chips'). The replacement cartridges arrived quickly and worked perfectly!If you are looking for a good quality ink cartridge replacement from a company with great pricing and strong service, I can recommend Kingjet.

These are garbage. A bright red comes out dark maroon, it doesn't consistently print black in the same shade, and on really bad pages it bleeds black ink all over the page in horizontal stripes. It prints half the images on a page (inconsistently). My printer doesn't think all the cartridges are full despite being new.I have tried every troubleshooting method I could find in order to fix this, with zero success. (clean printhead x2, align printhead, cleaning inside of printer). Sometimes they print fuzzy and gray, but useable, and other times half the info/page is missing. If I hadn't been out of town for the return window, these would have gone back.I had ZERO problems printing for months with HP Instant Ink, just wanted to get out of the cycle of paying for it and save some money. This was not the way to do it, apparently.

I bought Kinjet ink a number of months ago when my company provided a printer. I expected that ink that came with the printer would not last too long, and I was right. I purchased Kingjet ink due to the price and the customer feedback.When the printer ink ran out I tried the new Kingjet ink. I was shocked when the ink cartridge was not recognized by the printer. I was not happy. I thought about writing a bad review, and ordering something else.But, as I got ready, I read the Amazon instructions, and sent an email instead. Thank gawd I followed the Amazon instructions. That was the best thing I have done in a while. Kingjet got back to my email very quickly. At first, I thought it must me Amazon, but no, it was actually Kingjet. They told me why the cartridges were most likely not working, and I am convinced there were right.I was offered my money back, or new ink. I was also offered my money back if the new ink did not work. This was all within what seemed like just hours.Well, the new ink worked great and looks great, too. I like to feel like I am getting what I paid for, and when you put great service from KingJet and Amazon along with it, I call that a winner. I will stick with Kingjet as long as they continue to put a smile on my face.

I bought like 4 or 5 packs because of my subscription but 0 of the cartridges work due to a chip read error and the ink isn't the same quality but you get what you pay for. I ordered this product to print custom 11x17" calendars for my brand and am overly excited about it! I have possibly NEVER GOTTEN A WORSE DEAL IN MY LIFE! Thank you Kinget my pockets and OfficeJet Pro 7740 thank you for selling us this non compatible product. #MilliUp

I had purchased these inks as a back-up when I purchased my new HP Printer 6 months ago. However, when I went to use them I found they did not work and that HP had done firmware upgrade. I then noticed that there was a new version of the ink that came put after the firmware upgrade. My inks were beyond the return period so I contact the vendor. They responded immediately and offered me a full refund or new inks if I would like to try them. I opted for the new "updated chip set" inks and got them in a few days. I installed the new ink and they worked wonderfully. I really appreciated the customer service of this company. It is nice to see a company stand behind their products. I will be buying my next batch of inks from this company again. One note: HP sends out firmware upgrades that could render these inks useless. I have no idea how often but one solution is to turn off auto firmware updates (check the net for your printer type for instructions). That way you have control when the upgrades take place and can check with the ink vendor who seems to keep up with the firmware changes and update the software when new inks match the firmware version. Thanks again for the wonderful service!

Bought this as a bargain deal over original HP inks. Price is OK. Print quality is also OK. But it took 3 retries to actually install and recognize the blue cartridge. After installation, the HP Print manager accurately reports that the ink cartridge is not an original HP product, but surprisingly, the levels of ink are completely different between the 3 color cartridges. Blue shows full, but the other two show about 60% full, even though the cartridges are brand new. Also, the plastic parts that actually go into the printer have a very rough finish. I guess one gets what one pays for.
