As you probably know, the biggest complaint about having a windshield is the additional dust and heat. If there is a product that can help to reduce some of the additional dust and heat, I am interested, but I was hoping to get feedback from those that have used one of these reversible heaters, as to whether it made a difference. I get that it will not be perfect and I am not expecting a Benz, but why not improve things, if I can. It is like the clutch noise that everyone complains about - If you can take some steps to cut down the noise by 20%, it is worth it to most people.
