Value for money. Print quality after Refill good. Best to let it sit for some time after Refill or use suction tool for feed Results. Had issues like "Cartridges not recognised". after refilling. Expect this with black Cartridges. Remove the original paper seal over the holes and there is a chip with glass. That's the culprit + software update by HP. Problems like cartridge not recognised is because of software by HP that is built to stop refilling. Just a thought: When I brought the printer, hp recommended I use Cartridges from HP. I didn't sign a contract that I will always use new Cartridges. Can HP force stop me from refilling ? Is it legal on their part?

Decent quality at a very reasonable price. 4 bottles on ink (black, cyan, yellow, magenta) provided with 4 syringes and a lot of polythene gloves. Since only 3 - 7 ml of ink (of any color) is used in filling standard cartridge, the bottles can last long. I made two holes (using the syringe provided) in the silver foil covering the bottle mouths instead of removing the foils completely (to prevent ink evaporation/ drying). Would recommend buying a suction tool as well ... otherwise the cartridge sponge might not soak up the ink fully making you think that the inks don't work (they work). Also, fill the cartridge before it runs dry (so that the inner sponge in the cartridge does not dry up).

Not useful. Product quality is not good

Bottle seal was open.. maybe you have sent tampered item. Ink was spilled all over box.. ink viscosity is less... It drips from the nozzle when filling and after cleaning I have to waste 2 or 3 paper for the print to set right. Colors get smeared on the paper

It is very important to read the instruction and check how to refill the cartridges on the youtube. Very important to note is that HP printer does not recognize refilled cartridge and hence, one can get confused if the refill does not work. Please ensure that you reset your Printer so that the refilled cartridge can be used for printing. Also it is very important to understand that very old cartridge or not clean cartridge can be problem; so better clean the cartridge and refill the ink. The refill inks are really good, just that one should understand how to refill and how to reset the printer before the refill cartridge can be used.

Received product as specified, filled cartridges upto 3 ml in color and b/w. After leaving 3 hrs and checking flow I printed few papers. One 2nd page yellow was gone and on 3rd blue gone. So had to refill again. Also it dries up very quickly. Didn't print any page for 2 weeks and Ink was dry... I covered ink holes properly on cartridge. Overall I was not expecting quality of Ink to beat original and this product paased that expectation very well... cheap remains cheap.

Works for refilling HP703 . One needs to make sure the ink has not al;ready dried up in the cartridge. The online videos are helpful, and easy to follow instructions. Looking at the three uncovered holes, its easy to look and identify which colour goes where. I only replaced the colour cartridge , as the black cartridge was already full. So the test was primarily for colour. The 1st attempt - resulted in no colour print. I had to remove and cartridge and then use the suction tool (purchased earlier , separately). After drawing out ink from the suction tool (it looked like only one colour came out), the printer was able to print colour. There were some stripes in the yellow print. However later in the day I was able to print colour photographs. Sample of the 1st printout is shown in the review. Overall I seem to be satisfied. Prints are not very sharp/bright, but ok.

it worked fine for me i have HP 3520 Printer Which uses HP685 Cartridges, Which Are Very Costly But I found This Product At Cost Of Single Color Ink Cartridge Very Amazing And Fine Product ! but i dont know why have to refill it in 2-3 days but not fully refill just 1 drop but its nice product no problem Thank You Team WhiteSky For Providing This Product.
