Deletes reviews on their websites. Most likely pays or have paid for reviews. Snake repeller vibration product doesn’t work as the vibrations would have to be massive like a car driving over speed bumps or you would have to buy heaps and have them around 10cm spacing. Also shouldn’t make noise as snakes don’t have ears and cannot hear anything. They sense by their tongue. They also block you on social media if you don’t agree with them or point out correct things, which mislead consumers. Other products maybe ok like mosquito net. But snake repeller waste of money, keep your grass short, keep it tidy and no hiding places and best to leave them alone or call a snake catcher.
