And yes, another one here who is having a very comfortable (upper) Hawley.
I posted about it some days ago :
viewtopic.php?t=16954
I do not know if you read all my older posts, but I had Essix retainers before.
So I can really compare now. Yes, the Essix is less visible. But in my case there
was always "bubble-ish" saliva between my teeth and the inner surface of the
Essix. It was like my teeth were in some aquarium with some oxygen pump built in.
There was also gum surface that was in the retainer too, and that didn't feel right.
No, I prefer without any doubt my new Hawley. Yes, it is now a lot more visible that
I have a retainer, but somehow my teeth don't feel so trapped anymore. Because there
is only that wire that goes in front of the teeth, it feels more just like braces. One issue
though, I too have a very serious lisp. My Hawley has an inner spring and is therefor
quite bulky behind my front teeth. But it gets better everyday. I notice my family
members again understand what I say

. And like Chris said, they are adjustable
a bit, Essix retainers not. So, I too can say that I love my Hawley, and that helps to
get motivated to wear it all the time, like I am supposed to do. Oh, and why did I get
this Hawley ? Because my Essix retainers could not prevent that my teeth shifted quite
a lot. The Hawley will not only do better, but even correct this unwanted movement,
hence this spring. Only got this Hawley 5 days ago, but it seems to work well.
