It's all in Japanese, but onahole.net did review Ju-C Air + Custom Maid 3D.

I did write some comments about the older 3D Custom Girl and Custom Maid 3D looking at their video demo: http://blog.onahole.eu/game-controlling-onahole-the-future-is-not-yet-now.html

Technically it's getting very interesting. AnonymousD's also keeping an eye on it ^^ http://boards.onahole.eu/b/res/28.html
But still: there's space for improvement, like adding more sensors to make the simulation more accurate (instead to have the game "jump" from shallow insertion to deep insertion).

Investing that much money I guess that's more a "2 years investment", but I think there will be new stuff until then. Wait and see, Google's opening a treasure box by developing the Google Glasses :)

Sounds great!

Guess I'll take your advice and wait and see where this technology goes. I'll settle with a regular onaho for now, thanks for the help!
