i loved my unger ali pole, 3 X 2 M, it lasted and lasted and lasted
then i tried the Ron Thompson zensorflex, it took 15 mins to convert ( which was sticking a short length of unger ali pipe on the end ( only to take the brush fittings etc etc )
my RT Z-flex is now over 1 year old, it cost me 21 quid delivered, this does every1 of my domestic houses ( no 3 storey houses though ), but if you have some of them, you can spend a extra 50 quid on a gangsta and you have a pole that will do it all
BUT
forget the cost though ( but for 21 quid, what have you got to lose, you are familar with the modular pole use, so you know what to expect )
its the lightness that does it for me, stick a lightened ( or light brush ) on the end and you have the lightest you will ever get
how much -- 21 quid
where -- google Ron Thompson zensorflex (THO-88018)
job done
