Thank you for asking. She's doing fairly well with them. She was required to wear them 22/7 for about six weeks, then the ortho moved her to nighttime-only wear. She does forget occasionally, so I remind her and sometimes even have to wake her and put them in for her, haha.
She prefers the Essix for comfort, but wears the Hawleys a lot just because I prefer them. The Hawleys still induce a lisp, which I find charming.
I really need to have her make a video comparing the two retainer types.
