We are contractors and this came in handy just at the right time.  We were working on remodeling a bathroom that does not have a window.  The Triburst Deluxe came in handy just at the right time.  With no natural light it is hard to apply the group properly.  The Triburst Deluxe made the room look like it was under a microscope.  Thanks so much for the easy to install and use moveable option.  Highly recommend.
