The medium mixed hybrid will take some getting use to. I'm finding it very springy on the glass and for leaded windows it's nearly impossible to get good contact, although if you turn the brush ever so slightly sideways it's alot better.
Cleaning wise it's spot on, I'm parked in a cul De sac doing 5 houses this morning so iv had a chance to go back and check windows once dry and they look ace.
Just annoying that every house has leaded fronts, was tempted to put my tecbuk back on as that copes with lead a bit better but I want to keep testing the supreme.
