Use this grade anti-fogging agent for several years, several times a week. In the old drop-dosing, there were never problems with the action. This means applying the slightly thick film with a finger rub, rinse with clear water, ready. Unfortunately, the composition of the spray bottle for the worse seems to have changed back. The consistency is thin and watery, the actual, active substance is hard to feel with the fingers when rubbed even more.
Result: There remain after rinsing places on the glasses without protection, thus these fogged partially very fast. Only repeated spraying and let it dry, so a higher concentration helps. That can not be. Effect and consumption are completely unacceptable for this price! In my opinion "theme missed"! Therefore, by me only one star.
