This is amazing. I live in Palm Springs and it's hot hot hot in the summer. Even with the blinds on, the steering wheel feels hot, not to mention the cabin is so hot it could make you nauseous. The umbrella lowers the temperature and makes driving a little more bearable. It is best to practice putting on and taking off your car a few times at home before putting it in the parking lot. It draws a lot of attention and if you put it up clumsily it can be embarrassing. I know from experience! It took some wind, but I wouldn't leave it in strong, sustained wind conditions. I think I'm the only person in Palm Springs who has had it so far. There was a lot of interest in him and a lot of questions.
