Bests & Worsts Reviews from Amazon

The calculator works perfectly. The paper was easy to install and it feeds great. Why two stars? Nowhere on the Amazon product description or on the box does it tell you that you need an ink roller. It tells you this on the instructions. For some reason known only to Casio, the calculator comes with an IR-30 ink roller, which is used by the factory only for testing. The correct ink roller is IR-40. The calculator comes with a starter roll of paper. Why couldn't it come with a starter ink roller as well.
