I like this kind of pole a lot,... but I can't wait for a new one to come on the market. Something stiffer and lighter, without the sticking or swivelling problems. I've been looking at poles for a while,.. If I can find a suitable one, I'll buy it and just remove the clamps and fit a stiffer pole hose to hold it up.
Clamp-less really is soooooo much faster on domestic work. Until you try it you just can't comprehend how much faster it is!
