The product, apart from being nicely packaged in its box, comes complete with syringes and needles for filling, a clip for removing excess air from the ink cartridge, and of course, bottles of ink as well as a bottle of ink cleaning fluid in case it hasn't been used for a while. The instructions are also very accurate and detailed. After all, we're not talking about nuclear physics, just a little caution and following the instructions is needed. The printing result is very good. Although I haven't printed on photo paper yet, on regular paper, the quality is perfectly satisfactory. I can't find any difference compared to genuine HP ink. I use it for household purposes, such as printing photocopies, photos, and many papers for my daughter's school assignments. The savings we make are significant. The cost of the set is equivalent to genuine black and color inks, plus a little more, with the difference being that with the set, you can refill the corresponding inks multiple times. Additionally, the inks provided by Eurojet are priced very well in relation to the quantity, and besides, we will only have to pay for the ink and not the whole set. I recommend it!
