By 16x you mean 16 normal sprays.
Thats 4 sprays of the 4x version.
Well i tried 3 sprays with great results. But 3 sprays from 2.1.
If this was a normal shine 4x i would say you will probably be out of this world for 5to10 min…
I dont wonna rush in conclusion but there is something allot different in 2.0.. ??
I have to test it a week or so and i will post my full opinion on it
The reason I say 4 sprays of IS4X 2.1 wouldn’t be the same as 16 sprays of IS or 8 sprays of IS2X is because the diffusion rate is different between the two, and in my experience the feeling is different. Yes, they will both get you happy, smiling people at any range over 5 sprays probably, but I just feel that the difference between IS2.1 and IS2X is significant, due to the diffusion rate.
