Last year we saw OnePlus open a 'OnePlus Experience' store in Beijing where the company not only let people try out their 2014 flagship killer, but also see their other accessories(like the power bank). It is being reported that the first retail sales(in limited quantity) of the OnePlus 2 will begin on August 8th in this very store.
