MotionSense is great for people that is not very confidant when it comes to freshness and protection. When i used other roll on products i felt sweaty within hours of application. I have found that soon after application i have no worries of roll on sticking to my clothes or reapplication during the day. I don`t have to carry it in my bag for reapplication and i don`t feel insecure with MotionSense. I have to admit i was very skeptical as i have very sensitive skin and i had no problem. It actually made my skin feel soft and i had very bad burns of previous roll-on and it actually lightened the dark skin under my arms.
