I’m reading these reviews, and I can’t find a review with somebody who has actually bought or used one??? Which to me is highly suspicious. It might be a scam, but it is logically questionable why all these people – having never had one, feel the need to leave negative reviews? Are these people from energy companies? Or are they people involved in this item, herding people into thinking they need to buy one? 🤔 highly suspicious either way!
