Great product
I've been using the Epson refillable cartridges and ink from MIR-AUS for many years on an XP850 and now an XP950. The printers are at home and only print about 1 page per day, therefore I buy a set of 100g ink bottles every couple of years. The cartridges are originally from my XP850 and now in the XP950. I guess they are about 8 years old and still working happily. Apart from the occasional rejection of the cartridge by the Epson software, which is always overcome by re-inserting the cartridge, the MIR-AUS cartridges work a treat. The ink is also reliable and easy to refill. It also saves lots of money.
