Wow, that looks like a pretty exact clone of the Casio FX-350MS [1]. Apart from the colour scheme, the shape of the directional keys, and some of the lettering, they're identical.

Yeah, it's clearly a knockoff. They even borrowed the idea of having five red, dot-separated letters above the screen. S.U.P.E.R. probably means nothing, but if Casio has it, Kenko must have it too.
