In what way is it different? I've just looked at the Unger carbon tech pole which is water fed through the middle of the pole etc. in sections. Very pricey and just can't warrant the big price tag. Even the weight is dissapointing when a heavy flow tap is added onto the pole.
So what is so good about this replica!!!
It seems to me, that it works out cheaper buying several different length poles and using the appropriate one for the job, and if one is out of use at least you have a back up.
Just my opinion!
