While I agree that Richard is, how can I say, a little outspoken,
I find the the Tecbuk brushes outperform the gardiners brushes for speed and cleaning of glass on maintenance cleans (red bristles dual trim) their quality is far superior to the mass moulded gardiner brush,
Yes a little weight loss would be good, but in this world you can't have everything it seems....
The hogs hair really blows any man made bristle brush away for soffit fascia gutter cleans.
The black nylon version isn't much cop tho.
