I have received today 10 cartridges for just under 10 euros. Have exchanged directly against the original Epson 18 / 18XL black cartridge. From the dimensions of it are absolutely identical. While the Epson bleats on the display that this is not original cartridge, but without any problems after acknowledgment. The first pressure took a while, probably, he had to set briefly, then as usual immediate pressure. The new level was shown. Highly recommended. Each cartridge was vacuumed separately and sent in a handy cardboard envelope. Price / performance, at least for me, very good.
