No worries, these cartridges are perfectly compatible with my printer (Canon Inkjet i560) they do not dry in the printer (I have them for several months) and are ideal for the quality I was getting with the original Canon cartridges. I think the problems of other comments from the fact that they forget to look at whether their printer is compatible with these cartridges or they forget that any printer can NOT make exceptional quality for printing photos ... This is the case of my i560 for example ... The trick is to know BEFORE buying ;-)
