Langham Place in Mongkok, L'hotel élan in Kwun Tong, Holiday Inn Golden Mile Hong Kong in Tsim Sha Tsui, Prudential Hotel in Jordan.
They are near the MTR station and very convenient to go to the venue.
I got it together with ShengShou 5x5 yesterday.
I think I did about 50 solves with this cube to adapt.
It's a pretty nice cube although I sometimes get stupid lockups.
I think it will be better after breaking in.
So if you are looking for a new cube,I recommend you get this one.
