Won't hold shape!
I have reshaped this 3 different time.  It will not hold a shape like a wider &#34;U&#34; shape so it squeezes my teeth toward the center until it hurts.  If i try to reshape it, it only lasts a little while before it does it again.  I don't need my bite reshaped.  Now I can't return it or even get my money back.  This product is useless to me.
