It works
The maker was very conscientious & followed up with me.  The product appears durable & seems to do the trick.  I will spare you the details of how it works…but I really think it works.  I have noticed that my mouth feels & smells fresher in the morning since I’ve been using this product.  It doesn’t seem to hurt either – that was a concern of mine before I bought it.
