Travel back, I come to you; I already wrote to you there a fortnight and still unanswered about this shipment of cartridges that are defective: can not enter in my Canon printer MG 8150. This is the first time I such boredom. I tried 2, and no one will. I dare continue the tests ... have you had other feedback from your customers? it would be nice to trace these remarks to your provider. I await your response to this message, hoping to have more chan that the first time. Sincerely, Paul SAUVAJON
