I have been testing experimental ishine the last 2 days 
2.0 and 2.1 once each. It seems to me that 2.0 works better and last longer than 2.1.
I only wore 1 spray individually each of the 2 days since it is 4X. The self effect are also stronger with ishine 2.0. Friends seems to be more upbeat and excite for almost anything with 2.0, but 2.1 effects are more calm and deep to me.
I will elaborate more once i try them again, and again, and again…
