I have had my love bracelet a year and 3 months roughly and i have NEVER tightened the screws since the day it was put on my wrist
Id say it's not normal for it to loosen often
IMO it should rarely need tightening
I agree with this. My SA said the same thing to me when I asked if it can loosen from time to time. They said it shouldn't loosen but it would be good to just check it from time to time to make sure even if it wasn't loose
