Like the first movie, this one is based on the same premise. But there is two differences between the first AER (which I give 3 out 5 score) and this one.
First off, there is a lot more b-g action in this movie, it seemed that several of you disliked the lesbian action of the first movie. Secondly, there is only one scene of any ASFR content worth mentioning in the whole movie.
Of course same format as before, 5 scenes, 90+ minutes. The DVD is definitely well done.
Scene One has the star of the film Cathy Barry and two dudes. The same startup scene as the first, the two guys comment on how much better the ol' professor has done with the new model. Besides not much worth mentioning on the ASFR side.
[/i]The two dudes from this scene are the same two from scene two of AER Volume 1.
Scene Two (This is the best ASFR Scene of the movie.) Two guys order the newest AER model (Laura Ranger; She is also in Sin Twins) is delivered and activated right there. The actress stays pretty until her cue. Once activated she goes identifies herself by number and ask to be named. Nice monotone here. They go through the sex and at the end, Laura's batteries run out. (Great shutdown, interesting after the experience these two brain surgeons don't know if they want to recharge her or not.)
Scene Three and Four (Ok, start-up) but that's it. Even scene four could be a better scene if the writing was better. A guy comes in and rents two AERs, once activated -- they seem more interested with each other than the guy there satisfying. (Could have been a great malfunction scene. darn!)
Scene Five - It's an unusual variation because the two dudes from Scene one are playing the robots by rented out by a rather average woman. (Not really my cup of tea).
On a whole this movie makes up some of the sound F/X and music errors from the first one, but a lot ASFR makes it a lot less exciting for this group.
Rating 
½ of 5 sprockets.
Just one malfunction scene would have been nice.
(Ok - They are both pornos).
