I was six months repair. Imagine that during this time was with the windows? They are, of course, tried to wash, but because it did work, think that they are just dust smeared on the glass. This magical pshikalka, smelling something pleasant, handled the first time! I kind of waiting for something like this ... but to immediately shoot out a window and wash for 5 minutes - from the realm of fantasy) Honestly tell you: this is my first cleansers with Herbie, so do not compare too much with anything, but definitely better everything that is sold in Moscow shops. On the mirror is not tried - will edit later review. But as long as I have the most pleasant experience! Windows, by the way, the usual soap Microfiber rags. In general, I love it! Already I ordered and other facilities of the company.
