I have been using the new extendo pack in place of my normal Ishine.
4X 2 sprays hair and back of neck (my hair is up)
I notice the same great upbeat happy friendly vibe as I do with my 2X. Perhaps a little more prominant but not by much.
Normally Ishine will last me around 6 hours and I begin to get the tired crashing feeling. This still occured right on schedule for me. My crash effect may be cycle dependant as well. I notice certain times of the month Ishine will make me crash and others times I seem to be adjusting to it fine.

This one smells different to me for some reason. Not bad but just not like my normal Ishine.
I used 2 sprays, Hair and neck. The post master was considerably more giddy and teasing today. He always reacts noticably to Ishine. It did seem to last maybe a hour or two longer then my regular Ishine. I was getting those happy upbeat reactions well after I was done with my route. I did notice less of a crash effect with this one. I am not sure why and will have to test more to see if it was a fluke or what.
