This here is my first attempt was even refill the cartridges. All I can say successful experiment. The refill is very easy, but a small drill you should have to hand to enlarge the holes. The print quality is excellent. I can not tell the difference to a newly purchased cartridge. In set included everything you need. (Even gloves) But the best part is of course the price. Despite nearly 10 shipping to Austria a real bargains. Especially if you usually pay for a black cartridge 20.
