I can confirm that everything is free during the two years. However, the ink supplied goes a long way. I printed about 1000 pages and 1/3 of the ink was used up. I didn't know this from my HP Photosmart, so I bought cartridges bit by bit and had the feeling that the ink was still evaporating.

All free of charge. But so far we have only used 1/4 of the bottles that came with the purchase and in a few months the Unlimited will expire.
So if you don't use 1000 sheets a year but 500-1000, it's not worth it.
