I will allow posts as long as they deal with lasers and are presented in a way to help others learn both the good and the bad regarding wavelengths, companies , whatever.
As far as anyone being immune, all companies (many of which lurk and never contribute)are welcome to extole, and defend the virtues of their particular laser, some however choose not to. I guess we will let each visitor use their own imagination as to why.
This thread is now locked- the purpose of this forum is not to criticize companies. The purpose of the forum is to ADVANCE laser dentistry.
