Total scam ordered a device to examine its claims I wassupplied with a boc containing a device that looks just like they show on their but but it is not an energy saver. It is a vermin repellor sold under the name ‘Just for better space’. There scipt on the web site is total techno garbage which cannot work from a device that plugs into a socketvon the ring main.So if you want to repel vermin consider this device.
