Went to nearby shopping mall to shop and dine this evening. While browsing at a Home Fix shop, I came across this product "Auto Cool" which claim that it can cool down your car when it is parked under hot sun for hours. Almost tempted to buy it but the price tag prohibited me. And thank goodness, I did the right thing of not getting it.

Here's the reason why. Refer to http://www.nbc4.com/dirdt/9733390/detail.html. They have tested the product and it does not really work at all! Phew! Money still in my wallet. :)
