Is it just me or??
My brushes never seem to last, they always start coming loose ie start to swivel, and then I have to fiddle around with extra electrical tape, or stand on my head and screw the g-fit in one more rotation, I literally almost had to stand on the brush to make the next turn, but one turn less, and it swiveled around again. Right now, I'm dreading to take it off to use it on my Super-lite, because if I want to put it on the SL-X again, I had to go through the whole thing again.
Absolutely useless I find, maybe it's the aluminium G-fit screw head, maybe you don't get this with a plastic gooseneck, I don't know.
But seriously, I/we need an aluminium stock or something that lasts.
