I am still new and have had only two mm so far. They both costed me $140. The first kimchi was a 3 and disappeared after my review here. The second one from PH. They claimed her to be the most beautiful HK mm in Toronto but was very disappointed too. She left back to HK before X'mas.
Still yet to find a satisfying mm!!
I met her @ SG, never patronized SCS so not sure whether Chi Chi = Lancy. However, according to other others who met her in both places, confirmed Chi Chi = Lancy.
