Anyone got fan jets fitted to the extreme and rinsing brush on glass ?, as i think i would like to aspire to this and believe this is as good as it currently gets.
i have fan jets fitted in mine, but they do take out a couple of bunches of bristles.
I have noticed with my brush that it malts quite alot and the bristles are starting to get split ends, ive only been using it a week 
lol, i tried one the brush looked similar to how you described
it has too few bristle to be affective
it took twice as long to clean a window than my aerial brush
extreme brush isnt in the aerial brushes class
not by a long way
The aerial brush is made better than the xtreme, but the xtreme cleans just as well as the aerial brush, but is so much lighter, that is why i changed from the aerial to xtreme.
I dont know what you were doing with the brush for it not to clean the window properly, did you have the brush the right way around? or is it that you just like to slate gardiners brushes because you have a vested interest in aerial brushes?
Your negativity towards gardiners brushes isnt doing the aerial brush any favors because you are completely biased, but in reality the aerial brush is a very good brush, better than the SL DT mono, im sure more on here would have bought one if you didnt keep banging on how good they are and how rubbish gardiners brushes are, its getting a bit boring now.
