I've had one since I've had my scoot.
Works great, if it were a bright color it would be more visible on the scoot when I park downtown....just across from my dentist. So far the pager has yet to save me from the 'chair' though. Sometimes, when I get a bad feeling, I put it on out in the attached, locked garage. The alarm will wake you up.
Kinda heavy, which means I don't always carry it.
But I use the grip lock for quicker in & out at stores...bright yellow is very visible and it is quick & easy to apply it.
