Random amount of ink in some cartridges, if not full, recognition of random printer must be reset every time, so the risk of blocking the Epson chip. Poor quality of ink. Rather long delivery. Unsecure packaging, arrived damaged, risk of unexploded cartridges. Indeed, it was worth the money .... just the money! But the goal is still can print, lol .... not avoid if we want to remain calm, to each print. Very uncertain and risky product ...
