Have the Regenabweiser ordered based on good reviews and applied it for the glass shower and the car windows. The handling is made very quickly and einfgach. For the first experience I was quite excited, it worked, the shower was relatively easy to get dry, the car windows and mirrors Site without wiper clear. By now the third rain, showers and the third to reduce the effect was clearly visible. Already after 4 weeks is nothing left to see of the Regenabeiser. Contrary to the announcement, it hold 6 months, my statement was just a part of that time, so two stars less.
If you can live with this fact, it is very good and helpful.
