Disappointed, Can't use
If you have a small mouth like I do, these trays are way too big and bulky.  I can't use them.  If it were easy, I would just send them back.  I just went back to my old custom trays and I'll use them until they just break.  I'll have to find another solution.  Maybe they work better for someone with bigger teeth and a bigger mouth overall.
