1/5 Don't Bother
  by Billy Brown
The animation is terrible, the sex is boring and mechanical, the plot never goes anywhere and we never find out much of anything about the characters. Save your money.

3/5 The Sex is amusing more than erotic
  by Rapheal's wings (Pennsylvania)
The amime has a mediocre story line involving the destruction of some earth organization by an alien organization. the sex is between the mech users of earth and some spy with a captured girl, while this was interesting I mostly wanted to laugh.
