Has anybody tried (or heard of anyone trying!) invisalign invisable braces?!

VERY expensive but I hate my crooked teeth & don't want, at the age of 35, to have train track braces. Wondered if anyone knows if they are as good as they sound?

I am sure I saw an article recently, not about invasalign, but another type, almost invisible and did the job very quickly, in weeks rather than months.
I remember it being VERY VERY expensive though. Much more than invisalign. But it was the latest technology.
Can't for the life of me think what it was.

Thatnks littlelapin - just reading thread now!
