I'm always a little wary of using a cartridge other than the printer manufacturer's. And of course they like to scare you into thinking other cartridges will not work. I recently replaced my HP printer cartridge with my last HP cartridge. When I went to order replacements, I found JARBO's and saw how much less expensive they were. With a little hesitation I decided to try them and take a chance. In the meantime, after working for a few days, my official HP cartridge was giving a "faulty cartridge" message and the printer was not printing at all. I waited for my JARBO shipment, put in a cartridge, and got the scary warning. Bypassed that, and the JARBO cartridge has been performing just fine!! Thanks for the high quality and reasonable option!

I have a HP Photosmart 6520 that I use in my office for printing financial & insurance reports for clients. Usually 10-20 pages. These cartridges are about 80% less expensive than actual HP ones and work just as good.I love these and would definitely recommend.

The printer says they're counterfeit but they work just fine after checking the OK box on your printer. They work great and get the job done for printing! Great Deal!

Bought these because of the price. First one out of the box worked fine. I will be interesting to see how long these last. The overall cartridge is the same dimension as the OEM but the actual ink reservoir appears a little smaller as there is a 1/4 inch or thereabouts on the end is made of clear plastic. So even if all 4 cartridges combined only last as long as one OEM, for the price, that is still a bargain.

So far so good. I installed the XL black in the printer (it took me a minute to figure out how to install this cartridge) and it works perfect. The HP Photosmart 7520 printer detects that it is not genuine but I can still print with it, and it shows the cartridge level as being full. I already ordered more from JARBO because I need to get Photo Black, and the colors were running low also. I was able to get this FOUR pack of XL Black ink (~$10) for about 1/3 the price of ONE genuine OEM HP XL Black cartridge ($30)

I never buy off-brand ink. I don't because I had a bad experience a few years ago. What a mess! Then, four years ago, my home was robbed. The man entered through my office wndow and I left his footrint on my window sill to remind me to never let down my guard. The robber stepped on my printer and I patched it back together and after much work, it printed again. This year I finally bought a new printer, but I still had good ink in the last printer. I debated letting the ink go or buying one more black ink for the old printer.In the process, I ran across this JARBO ink. It was so inexensive. Five cartridges for $9.99. I figured if it was garbage, it was cheaper than one drink out with friends.It wasn't garbage. In fact, it's far better than my genine HP ink. What?!?!?! How can it be this good? How can it last this long? THIS INK IS SO AMAZING! How do they do it?I don't know how they do it, but it's the best ink I've ever bought. I 1000% love this ink and recommend it to everyone. It's the best I've ever bought. When I fnally get the new printer out of the box... I'm buying this ink!

Purchased for use in my HP7520 Photosmart printer. MUCH, MUCH cheaper than HP cartridges .However, the cartridge leaked ink (onto rug) when I opened the package. Nice black stain on tan rug! :(That said, it does print fine now that the cartridge is installed in the printer. So . . . . . . you get what you paid for!………I originally posted the above with a 3 star rating. JARBO contacted me via email with apologies and offered to send me replacement cartridges at no cost. Obviously, they really do care and want to stand behind their product. I gather the leaking cartridge is not common but can be caused by vibrations and/or temperature changes during shipping.As noted above, the cartridge performs perfectly once installed so perhaps it deserves a 4.9 star rating. We shall see once we handle the rest of the cartridges.In the interim, I expect they will become my new cartridge supplier unless I experience additional problems.

Bought this a few weeks ago and have used my printer numerous time and I am very pleased with this ink. It seems darker than standard HP ink, but that could just be from me seeing my old ink get lighter as it ran out. I got an error when I put it in because it isnt HP ink but just click on OK and move on and it will be fine.
