I like fact its not removeable, one less thing to do when locking bike up. I've has intuvia come off when push though heavy brush, luckily found it again.
I place bell next to purion to give it some protection. Whether its purion or intuvia plus remotes still vunerable in crash. Specialized system with small remote buttons is best, not sure if can still use assist on side of battery if remote is damaged.
Found I spent to much time looking at Intuvia than countryside, purion is less of a distraction.
