I have also tried one and I had a similar experience but only in some scenarios. It might be a different effect to what you had but I’ll try to explain.

In my experience I got a good 3D effect for objects that were right in the center but the moment things got close to the edge the illusion broke. At times it did look a bit like 3D content on a 2D screen.

Objects near the edge of the retroreflective area disappear when you would normally expect them to appear ‘above’ the mat. They somewhat get around this by presenting most information below the surface. Apps like board games were the worst for it because they typically use the whole mat and they typically appear on or above the surface. Anything above the surface just gets cut off around the edge. The larger board that can be tilted up at the back helped but only from one angle.
