I tried black ink today and it printed absolutely fine.Do not worry if 1st print is not proper.solution is : place small cloth over the part from where you injected the ink and blow air with mouth.You will see little dropa coming out from other end. Just soak them in cotton and try again .Thanks.

Though after filling the cartridge , the machine shows partly filled and after a while shows cartridge empty, but printing job very well continued. Needed no refill till actually printing faded.

Do not waste your money on it... The inks are diluted and water-like in texture and consistency... They should be a bit thick... The catridges are leaking after just 1ml of refill... Indeed, a real nightmare...!!I learnt why people always recommend buying Original HP Ink bottles...

The product packaging and delivery excellent. But the ink quality is slightly on the dull side. The colors what the print is producing too dull. The print diagnostic page has Black color similar to that of Dark Grey...and sometimes a yellowish tint is visible in the black print...Overall average budget ink.

If you are looking for a cheap alternative to the pricey HP/Canon cartridges and are ready to compromise on colour quality, you can go for it. It goves okeyish prints for regular use. Prints are nowhere close to the output of original cartridges. Look at the attached picture, especially the red colour printed with this ink; it is nowhere close to red looks more like orange. This kind of output is not at all suitable for printing photos. For me it was pure wastage of money as proper color reproduction is of utmost importance to me.Better to try refilling the original HP inks (GT52 series). They are costlier but will give better quality and qould definitely be cheaper than buying cartridges every time.My suggestion, stay away from these aftermarket inks, its always a case of hit-or-miss. If you do not mind the color reproduction accuracy part, then these are pretty good economical choice for usage around the house.Edit: (23/3/22): Today I flushed the cartridges of the old ANG ink and refilled with original HP ink (GT52) bottles. The results are far superior and exactly like the original cartridges. Check the second image attached for colour reproduction. First image - ANG ink; Second image - HP ink. The difference is easily evident. I am happy withthe results this time. I paid around 2000 for allfour bottles of HP ink and will easily last me for around 12-13 refills which is much more economical compared to buying cartridges.

The product is very good. I got the whole kit mentioned in the description. It was easy to use n after refilling the cartridge the print also came veey good and clear. I have attached a print after refilling n cartridge performed really good.

The ink is a bit thin compared to other older products...printed pages tend to smudge initially but correct upon two runs...the cartridge slot is incompatible with hp 678 catridge size once with the silicone suction pad inside....without it, works fine.
