Fortress = definately the 1. as they 100% sell real thing & is owned by the richest man of HK KS Lee. so no worry about their svc & quality.

although there's some hidden point 4 the locals to shop 4 gadgets but.... afraid some of them wil cheat u. the most famous electronic street = Ap Liu Street.... but is a v v local place. beware!!
