Energy bills are on the rise and winter is coming. The solution? How about a plug-in box which promises to save you money by making household appliances work more efficiently. Or maybe you can drive down your usage by putting in a “voltage regulator” that can cut your costs by almost a third.
The reality is that, at best, these “energy-saving plugs” or “eco plugs” will do nothing apart from bill you for a useless piece of plastic. At worst, they are dangerous and won’t even pass basic electrical safety standards.
