Upon receiving my order, the cartridges were defective. I sent them an email to 23h. From 9am tomorrow morning, I had an answer. He offered me an exchange or refund. After accepting an exchange, I received in the 48h of new ink cartridges and good to stick on the return envelope (assumed at 100%). After-sales service is impeccable. If only everyone was as professional as them. Also the price / quality ratio is the rendezvous. So despite this little cartridge incident, I repasserais by this site without hesitation ..
