I love the product. It was bent during shipping, but that is not the fault of Grand Illusions.

I like the hollow face illusion and its fairly robust. But its very expensive for what it is.

The illusion is good, but perhaps not as good as it looks in the video. It's very powerful in the video because you have no binocular vision to fight it. In person, the true concave space has to be overcome by your brain. But your brain does do it, and you can see the illusion, but you can also not see the illusion. When I see the illusion it is accompanied by a certain lightheadedness as if my brain sees the convex face but at the same time, on some level, knows it is not. It's an intri.
