Just a few months ago, we purchased brand new windows in our home. They, of course, we not cheap. These windows are Krypton filled, triple paned, and the sales person made a ton of cash on us. So, my hubby has been dying to buy a temperature gun to see if they are actually keeping the cold air (along with Superman) out of our home. When I got this MeasuPro temperature gun to review, he was thrilled.
