SainSmart MetaPhix M2 Graphing Calculator

[renif]

Hello Bob,
that label SainSmart may feel french (missing just one letter T), but isn't that a common phenomenon of smart marketing? About a year ago I have purchased an Arduino Nano clone called SainSmart Nano from the same source. It didn't work exactly as expected, so I read the customer reviews, where someone stated the device were fabricated in China. (I know, one should read reviews before buying as that's their purpose...)
Concerning the calculator: no tutorials and no information about RAM size. So I guess, at about the same price any used and refurbished graphing calculator from the four main manufacturers TI, Casio, Sharp and HP may be the better deal for the typical user.
