*Do NOT leave your blaster in the sun or heat for long*
Prolonged time in the sun or, say, a hot car can warp the prints on your blaster.
Avoid leaving the blaster in direct sun for a long time.
*Do NOT play without wearing eye protection*
I have seen many close calls. Always wear glasses or other eye protection when firing your blaster.
Always make sure those you’re firing at also wear eye protection.
