Living in Arizona, summers are brutal. SunDefix is an absolute lifesaver. It keeps my black leather seats cool enough to actually sit on, and it folds up so fast!

I love how easy this is to use. Traditional shades always slide down or take forever to roll up. This pops open like an umbrella and stores perfectly in my door pocket.
