I have one.
I do think that its great, BUT:
1. the pole swivels,.. you get used to it, but it will bug the life out of you to begin with.
2. the standard brush is a bit on the heavy side,... I put the autobrush switch on a lighter brush.
On the upside it is very fast in use, and not too heavy either.
It can stick in use as well,.. but there is a simple fix for it.
Peter is working on a new version of this pole which will not use tapered sections (so it won't stick), and each section will be shaped to stop them spinning inside each other. It may be a while before the new pole is ready for sale though.
I've more info and some pics on another forum,.. e-mail me if you want a link.
