Useless without grounding
I tested the sheet by placing it between the ipad (then my smartphone) and an emf meter on the other side. There was no change in values whatsoever! Ipad value 0.98 with or without sheet, even if this was folded three times = six layers! It has to be grounded to work, which I find troublesome when usind ipad or phone. Big disappointment.
