" I would like to take this opportunity to thank your office staff and workers for the courteous and professional service regarding my 8484E purchase. It is working fantastically.  I also appreciate the time that you took to have a window replaced through a window company in my neighborhood.  I now have the window in place and everything else is fine. There was a minor mistake on the window company's part in the first window ordered, but they fixed it. I will recommend the WhisperRoom Isolation booth to all I come in contact with."
