I just received my LUX and tried it out, once with Lloyd's "X" trick and one a repurpose of one of
my oldies but goodies.
Both worked like a charm. The method is well concealed and the UV
principle by itself encourages interest. The props are totally innocuous looking and I was surprised
by how small and plain looking the UV light is (can easily fit on my key ring) and looks like it
belongs.
The UV pen, btw, is apparently made by the "Barnes Ink Co.".....rrrrr, proving
that Lloyd does have a sense of humor.
The instructional videos are superb and promote
creative thinking. And since one can apply the methodology to so many types of magic and mentalism,
especially rebranding classics, the price is a bargain.
