Review on High Power Car Defogger: Fast Heating & Cooling Fan for Windscreen Defogging and Warmth by Jim Bethea

When I first received them I thought. JUNKY. one use is enough. Surprisingly, they are very well preserved. actually zero problems. more durable than they look if you use them with care. This. Think of an umbrella. I was even able to install and uninstall/minimize with one hand. with 2 it is of course much easier. Just keep an eye on the external viewfinders, don't bend them and you'll be fine. I find them lighter and more comfortable than the tent versions with expandable "sheets". I especially like how compact it is when everything is folded and stored away. Fills the windshield of my 2004 Nissan Quest. Just great (Very large minivan). No complaints.
