We'll test, so far one day carried D3 and I think that it would be better to take all the rigidity to gradually get used to them, because it is very painful to wear. I will supplement the feedback every month if possible, if there is an effect. I'm serious and I'm not in pain. And the seller thanks for the gift, almost forgot!
I received my order lightning fast. I have a slight curvature and I ordered a 2D, the jaw hurts after an hour of wearing, but beauty requires victims. I'll wear it. Time will show, waiting for improvement, I know it takes months 3. Thank you, the seller put the threads for cleaning the interdental space.
