It definitely doesn't hold 17ml. I barely managed to fit 4ml and it started to overflow. The 580 pages it claims don't even reach 1/10, meaning 58.

I was prepared for the possibility that the printer (hp4200) wouldn't recognize it, and that's exactly what happened, but the packaging was very poor. They sent me 2 toner cartridges wrapped in plastic wrap and tape on the electronic contacts. The ink spilled, and the whole "packaging" was pitch black. I cleaned as much as I could, but..... I do not recommend purchasing it.

Although it was immediately recognized by the printer and appears to be full (it is a refilled ink with genuine HP ink), unfortunately it did not print a single page. All printer checks show everything is fine. Its purchase is not recommended.

It works perfectly so far.

Update: One month later, it never printed anything again. Useless. Waste of money

Flawless operation. It was immediately recognized by my printer. I still don't know the volume of prints it lasts, but it seems satisfactory judging by the printer's application forecast

I opened it from the sealed box and it never worked, it produced blank pages. 15 euros wasted. I do not recommend it

I bought it because the information stated that it is compatible with my printer. Not only is it not compatible, but it stopped printing after about 10 pages. Obviously, the printer no longer recognizes it, so they should have mentioned it in the product details. 20€ wasted.

Very poor quality as the prints came out black only at the beginning, then after a while they started coming out green and finally the printer obviously no longer recognized it and they started coming out blurry and shaky, resulting in not being able to read what you were printing... I took them out before they even finished and got new ink cartridges..
