I bought this new on the recommendation of my doctor for the list price of 25,600 yen. It's a set of an electromagnetic wave (electric field) removal device and an electromagnetic wave detector. I used it for about three months and then put it away before moving, and I forgot about it. Operation confirmed, with instruction manual. The Plugin Earth, developed with unique patented technology, can reduce and remove electromagnetic waves (electric fields) from household appliances to a level that clears the Swedish regulatory guideline "MPR-II," a global safety standard for electromagnetic wave countermeasures. (Attenuation rate of 90% or more) By plugging it into a power outlet, it removes electromagnetic waves (electric fields) that are easily transmitted to people, in addition to computers, and cuts off the adverse effects on the human body. The Plugin Earth can be used alone for "electromagnetic wave countermeasures for computers, game consoles, electronic pianos, etc." Even when the power is off, computers connected to the power outlet generate noise of [electromagnetic waves (extremely low-frequency electric fields)] that is 10 to 30 times the standard value of 25V/m (volts per meter) according to the architectural electromagnetic environment performance standard (EMEAJ-01-2014). One effective countermeasure against this noise is grounding. This is a typical example of how the Plugin Earth®, which has shipped over 55,000 units, is used. Plugin Earth is the savior of 'grounding refugees'! By adopting patented technology, it is a unique and innovative product developed to enable safe and simple grounding connections in living spaces and offices without grounding terminals in outlets, without the cost of having an electrician install a grounding wire. For home appliances that require grounding, even in environments where grounding is not possible, it provides the same effects as grounding using USB, preventing static electricity and electrical noise, as well as preventing malfunctions, breakdowns, and fires caused by the appliances themselves.
