I bought an Hp ink cartridge from http://www.inkreplacement.com I think it was a refill but I am not sure, it works great though.

There are a lot of lookalike cartridge ink on the market. They look exactly the same as the original branded cartridge inks. I the price is too good to be true then it is probably a fake. You need to buy from a reputable supplier. visit our site at http://www.directink.biz
