Seriously! This is by far the best deal I've ever bought from Revain and I buy a lot of products from here. Each color works very well to my satisfaction! I'm so happy because as you all know it costs a small fortune to buy originals to keep us stock where I've often had to settle for just black and white. Now I won't either. Edit 2/10/17: After several weeks of printing with these replacement cartridges I would like to add that in my experience the ink lasts much longer than the original cartridges. I also noticed that I can see on the sides how much ink the cartridge actually contains. Double editing. I have just placed another order of these ink cartridges. This is my "transition" when I run out of ink. I've ordered them many times and they never disappoint!
