Nice print but the paper chews sometimes and the printer emits smoke if multiple pages are printed

You get what you pay for, I would give more stars if it didn't say 1000 pages but 100 (I may even write more).

Aftermarket toner, without a chip of course at this price. Logical. I didn't find any instructions inside the packaging for changing the chip, as someone mentioned in another review. I found them on YouTube, so it's not a big deal if your hands get a little dirty.
As for the volume of prints, I reserve my judgment and will add it to my review in the near future. The shipping costs are higher than half the value of the product.
edit: The package is both paper and not in the middle, and our toner ran out.... so you know how many sheets are in a standard A4 package, so you understand how many prints it made....

It doesn't produce 1000 pages as it claims, but for around 6.5€ that I bought it, it does its job compared to the original ones... It lasts exactly one month and I have it in the school office with a few prints per day.

The value for money is now of course the print quality on A4 paper and in terms of durability and color representation compared to the original HP is like day and night, but as we said for the money it costs 10-12 euros instead of 45-50 that the genuine one costs, it is definitely a perfect choice that is highly recommended.

The prints are good, and the ink recognized it immediately, I had no problem transferring the chip from the genuine ink to this one. The number of prints it will make will be shown over time.

3 stars because the prints were very few, around 300, so it's better not to bother with the chip. I will buy it again for a test to see if I received a defective one because I read in the comments about 1000+ prints, but I don't think so.

Update 5/10/20
I received a defective product, it had a broken latch on one side so it didn't close properly. I am waiting for a replacement and I will come back with a new update

For those who are willing to spend 5 minutes to install the chip so that the printer can recognize the toner, it is an EXCELLENT purchase. The print quality is impeccable, and the number of pages you can print is also great. It is a complete value for your money. I highly recommend it. If you don't want to bother installing the chip or if you can't, then you wasted your money because simply put, the toner doesn't work.

Exactly the same number of prints as the original, same quality and at an unbelievable price. The only thing you have to do is transfer the chip (1 minute). Literally saved...

Excellent product. I knew that I had to put the original chip in it. Without the chip, it doesn't work. No problem with the chip. Masterpiece. Quality is great.

First of all, in order for the printer to recognize the toner, the chip from an authentic HP toner must be used, otherwise it won't work. Also, once this is done, there is no possibility of reading the remaining ink in the toner, as the chip needs to be reset and this can only be done with some paid cracks available on the internet.
It is of course much more economical than the authentic HP toner, so if the above doesn't bother you, I highly recommend it.

A decent print quality. I couldn't manage to connect it to the genuine printer's chip so that the machine can read it and not indicate that it is out of ink

Very good choice. Don't get confused and throw it away if you see that the ink appears empty on the PC. The indication is completely normal and it prints perfectly fine.

Prints just fine. The printer flashes to indicate low toner, but it doesn't bother at all. And the process of transferring the chip is very easy. There are many videos about it.

I ordered a compatible HP toner and after a while it started producing black horizontal ink lines on every page. I opened it and the drum inside gets filled with ink and doesn't clean. Defective product.

Compatible ink. My first experience is very positive. The documents I have printed so far look very high quality. The only downside is that it comes without a chip.

Well, we all know that it is "compatible" and not the original, I bought it to try it out. I printed 3-4 pages to see the ink quality. It was like the original, no fading, no extra "stamp" on the paper, it's perfect. Now, as for the chip, I still get the "Low Toner" notification both in the application and on the printer itself. After calling the company that provided me with the toner, they told me to simply overlook it. These are my first impressions, I will edit again here when I learn more.
