The mandarin Mirror Box is very nicely crafted....the design inside of the box make it very deceptive...
You can actually produce a lot of stuff from it if you know how to organize stuff very well, just as OZ did in the demo video.
There is also a way in which you can make it look empty , by inserting your fingers inside of the box in a certain position, I believe OZ does it in the demo video.-
It has very little angle problems , it just can't be seen from the top; but no-one should notice it if you are doing a stage show and are a couple of feet away from your audience.-
It is an excellent production device for a stage type of show.
I would give this device a 10/10 , because if you are doing a stage show , people should not come close enough to inspect the box, or you shouldn't give it for inspection.I highly recommend it, and yes you could make one but it will be better to buy yourself a professional looking one.-
You can even personalize the outside of the box, as I did, to fit your show style and not that chinese coding or whatever that it is.....with a couple of spray painting if you are good at it........
BUY IT, AND PRODUCE THE PROPS THAT YOU WILL NEED FOR YOUR SHOW OUT OF THIS BOX!!!!
