Quite surprised didn't see any reviews for shuang shuang:

Looks wise I think she's quite chio, got mixed blood feel but quite tanned if you're particular about skin tone.
In terms of figure, slim build so boob lovers may want to look elsewhere.
Massage leh, let's just say I'm not visiting her for that.. quite comfortable la, but not the professional type.
Sensual, does what is listed on her ad.
Not the stuck up type and I enjoy every minute spent at her place. Treat her with respect and she'll reciprocate.
RTM: yes, considering she's new in this line and looking at how $120 seems to be the norm
Disclaimer: this is only my personal experience so YMMV.
