I don't mind Dell's insistence that one buy only their ink and only by delivery, but I've had several faulty cartridges, and if the faulty one is the last one in the house, one has to wait two days to get a new one. And, when I called to try to get tech help the technician took me through all the steps on their webpage that I had already tried multiple times. Only he took far longer as he studied and explained in a language that was probably not his first. I did get a free cartridge, but only after an hour and a half on the phone. Clearly not worth it. Next time I get another brand of printer, even though I like this 964.
