Ive ordered from them before, they are legit. I ordered carts for a Epson 600 and they worked fine, they are generic (G&G is the brand I believe) though.
Some people think generics clog your inkjet but I didnt experience anything unusual. Actually, with original Epsons my printer clogged once in awhile and I think maybe twice with the generics, just put it through a couple cleaning cycles and that fixed it.
Print quality looked the same to me.
