Having tried a number of different compatible ink brands, the Realjet ones seems to offer the very best value for money as the print quality is great, they are a fraction of the Canon Branded ones and to date the ink level reader chips have always works perfectly.

Didn't want to spend a fortune on refilling my hp printer so was pleased to find this set at a much cheaper price than some other sites. Only used blue so far and prints good. delivery was next day at mid day and packaging was fine.
