| Limitations | The shielding figures (over 99% RF, over 92% ELF) come from FCC-accredited independent lab testing commissioned by the manufacturer, which is stronger evidence than most EMF accessories carry -- but EMF Practical has not re-run or independently verified that test itself. By the manufacturer's own explanation, this shields the underside only: the top and sides of the laptop still emit, though at a greater distance from the body's more sensitive areas. Confirm your laptop's dimensions fit within 13.5 x 9.5 x 1.2 inches before ordering. | The shielding figures (over 99% RF, over 92% ELF) come from FCC-accredited independent lab testing commissioned by the manufacturer, which is stronger evidence than most EMF accessories carry -- but EMF Practical has not re-run or independently verified that test itself.

Like other lap-barrier products, this shields the underside only, not the top or sides. Genuine leather needs spot-cleaning and occasional conditioner rather than machine washing.
