Attracted by the price of these cartridges, I let myself be seduced but I should not have. Indeed cartridges were recognized but have created an error on my ESPON XP405 printer that is has now unusable. this create me a paper jam when there is no paper and it worked perfectly before with the official cartridges. The seller made the right thing, a refund of my cartridges, there were no worries. I turned on amazon for a commercial gesture, an official cartridge shipments may defer things in order but no gesture from amazon will not be done ... so if I had a printer 400euro cétait the same. Thank you for this policy ... Anyway without questioning the seller who has made the necessary level. I end up with a HS printer then believe me for some euro more formal cartridges choose at least you will have a maximum warranty on your equipment ...
