Review on ROYADVS Cigarette Windshield Defogging Defrosting by Wilzon Junior

Thanks to my knowledge gained in practice as an automotive professional, I can confidently say that this device is a total waste of money. The concept may seem good, but it doesn't work as advertised. It barely makes any difference in defogging or defrosting your windshield... The only pro is that it`s easy to install, but that's not enough to justify the uselessness of this product. Save your money and look for other solutions..
