Hi ggelb,
Yes in real life the effect looks as shown in the trailer. But note that is a bit angle sensitive and it has been developed for parlor situations where angles should not be a problem. To shoot the video we have taken care about angles to show it so close, but in real life your audience should be about 6 feet away.
So yes it looks so great as in the video, but is not suitable for close-up situations.
I hope this will help you.
