Long shipping: 1,5 months to barnaul. The package with chips was packed in a package with air bubbles. In the process of delivery is not damaged. I ordered 2 pieces at once. When unpacking it was found that they were made as if on one board with a propylene at the place of separation, i.e. Just break up in this place. Changing the chip is elementary and without any problems. After replacing the chip, the printer shows 100% refill cartridge. So i recommend.
Great chip. I took for samsung m2070w. i did not put it yet, but i take it for the second time. The first was enough for about 350 sheets (as well as native on the cartridge d111s). The first time the price was twice as big, so for 100r, excellent. Track tracked, fast delivery. Seller and product recommend
