Smells like bull**** to me.
Looks more like a glorified cleaning kit with some buzzwords like 'nanotech' on the packaging.
IMO, It would be very difficult for a spray-on product to have a uniform thickness and consistency. If it's not bonding in some way to the digitizer (topmost) layer then it's not doing much, and something that bonds permanently to that layer is even less preferred.
Also, the lack of any reviews online makes it smell like a scam. You would think with a 'new' 'revolutionary' product like this that the manufacturer would be aching to get it into the hands of a reviewer, or in the very least a preview on one of the major tech sites.
Now that I've looked closer at the auction/ad the spelling mistakes do not convey a high level of confidence.
Best to stick with a known reliable REAL screen protector such as Boxwave, Martin Fields, or PPC Techs.
