Is it April fools day allready?
Fans take a while to get used to, took me a month before i was sure i wanted to convert over.
Fans are much quicker, cover more area of glass when rinsing.
I actually prefer to rinse off glass, and lift the brush a good few inches off, as this will get you much wider coverage,so infact its quicker.
Just be a lil carefull on the top of the window, but there again even with pencils you have to be carefull here.
Myself, i hate pencils with vengence,and would never go back, each to their own though i suppose
