POLL: Lip implants

I've seen some discussions lately about lip implants. It seems quite a few models get them, even models who had perfect faces before.
What are your opinions on lip implants?
I would be especially interested in first or second hand opinions by models who have had lip implants and whether they themselves are satisfied with the result?
