It works top notch. A wet car so you can wipe it dry in a few minutes on the roof, bonnet, windows and trunk. This one has got almost the whole car dry.
I still drive afterwards with a microfiber cloth to allow any water spots, but overall the drying takes a limousine less than 10 minutes. It used to take my feeling after more than twice as long.
Moreover, it is very easy to use and the material seems to be durable and does not scratch.
White strips of rubber or other defects I can not observe at 15+ washes.
From me there is a strong buy recommendation.
