Put one of the cartridges in today and it goes like a dream

The cartridges arrived today, thanks. Very well packaged and such a quick service from Christchurch to Auckland. Ordered late Sunday night arrived first thing Tuesday morning, Isn't technology great. Put one of the cartridges in today and it goes like a dream. As you know I was worried about them before I got them. I will have no worries next time I buy from you.
