The best of it all is their new Vilkus adaptor. It was developed for people who like touching the electrical circuit with their own fingers.
Many people find pleasure in this unusual entertainment - they normally use U-shaped fragments of bare wire, paper clips or even usual metal forks. All these objects are unreliable and easily broken.
All household sockets are designed so as to prevent any finger abuse, while this adaptor lets to stick fingers very easy. For Brittish and American sockets - also not a problem.
A: Switch mode supplies could make it small. B: TMK, Europe, where this product originates, uses smaller 12V accessory outlets. C: It likely is a joke product anyways.
Of note, they forgot Aussie, BS1363, and BS546 adapters. Of note II, I generally hate those pop-off prong assemblies, and prefer an IEC plug arrangement.
