Great product, price and compatible with the HP printer. I ont hesitate when purchasing more when required.

I only installed them a few days ago so it's too early to know how long they will last. But I had no problem installing them and I found the quality perfectly satisfactory. I think everyone knows that when printing the black always fades first while the three colour cartridges are still fine. And most companies allow for that and always include a second black cartridge in the box. So when your printing starts to fade just replace the black with the second one and everything will be fine again. But HP themselves do not provide a second black in the box. Oh ! They'll tell you that you can buy a black on it's own but its all a money scam to make you spend more. In my local Tesco's in Ireland I found HPs pack of 4 (with one black) was €54.99 and then one black was €12.99. That's €68.00. I bought this order as a double pack, two complete sets, with two blacks in each for less than that. I have, on a previous occasion, in an emergency for something that needed urgent printing, gone to Tesco's and bought the HP pack and was shocked when I saw how short a time the ink lasted. Oh ! When you do your first printing with the new cartridges, a note comes up onscreen from HP asking are you aware that you're using counterfeit ink. Just ignore it and click continue. I've had it with HP. I'm very happy with their printers but not with their very expensive ink. Always read the reviews before choosing which alternate brand you want to buy. I was impressed by what I read about this brand and so far the reviews have proven right.

Quite impressed with these, compared to other non-original cartridges I've purchased in the past. You get a good selection of cartridges in the 10-pack box, usefully weighted towards black ink - and very much in line with my typical ink usage. The colours seem suitably vibrant. The only downside I've found is that, if I don't make regular use of my printer, I have to clean the printheads to avoid getting an entirely magenta image. Even with this inconvenience, though, print economy is vastly superior compared to using original cartridges.

We used them for HP deskjet 3520. ,no mess ,clean ,easy to fit and Perfect results. We don't know yet how long they last but good price !

impressed. after trying other brands and been so disappointed its nice to get ink that fits and works. well worth it

Have previously always installed genuine HP ink (364 cartridges) in my HP Photosmart Plus. Couldn't justify the cost and thought I'd give these ago as all 4 needed replacing. Thought I'd start with a single cartridge so just installed the black. The printer identified non HP ink and threw a warning. I removed it, and restarted the printer without any black cartridge, then reinstalled it and switched the printer off before closing the lid. Upon restart it performed a printer preparation all seemed fine. I then installed the other 3 colours in one go, restarting before closing the lid as before. This time no error messages were displayed but it did identify all as non HP. The ink level display worked and it successfully printed a print quality diagnostic report (see images) showing full ink levels and also a printer head alignment. I guess that the printer will store in its memory when non HP ink was first detected and engineers could interrogate the unit in the event of a warranty claim. This will be why it threw the original error codes and warnings. You may choose not to use alternative ink to HP in a brand new printer covered by the manufacturer's warranty. After this I'd recommend trying GPC Image.

They were a bit messy and my printer kept advising me that they were not authentic

I bought these last year as fed up with HP high prices and cartridges lasting for 12 prints. Amazing value at time I bought them at £19 but have noticed a big leap in price now to £26.42 still cheaper than HP of course. The last cartridges I put in from GPC didn't seem so good when printing out . The other advantage of them is you get more cartridges e.g 2 x black and 2 x colour cartridges. I assume with price rises and supply and demand these were bound to accelerate in price.
