There currently is yes the spring and here I see clearly that there are early in the morning when entering the car a partial achievement. The pillow I lay at night on the shelf directly under the front wheel. The windscreen is sometimes a bit damp, but sometimes completely free. On the front side windows you can already see a clear course and the further you go back in the car, the less clear is the view. A perfect result, there is probably not, but I have to say that this pillow helps reasonably well already.
However, one would have to work with two or more pillows to early in the morning to get any slices dry with a towel. Then you would have before driving but tuck until all pillow back safely, but this is certainly like to forget, when you once again comes to just leave the house to go to work.
For 10 you can no silver bullet against ice and wet expected, but when you compare this with other products such as dehumidifiers electrical equipment, sprays or the like, it cuts quite well off. In this respect, it should be in every car and let's face it, what can you do at this price already great wrong?
