Who needs these expensive glorified poles
If its just 17 foot get an Extel use them for a year then chuck em away what r they £70?
ive had mine for 2 years could use a new one now thou!
Sorry i wasnt much help 
the 17ft xtels are crap thats why, when i started wfp i had one and it was beaten after 3 months, there very bendy and wear out fast, waste of money i wouldnt buy another even if it was 20 quid,
i agree, the extels are crap.
i use a 18 ft slx for most of my domestic work, and ive had the same one since june last year and is still going strong.
i used to wear out a 17 ft extel in about 6 months, so to me , im saving money.
also last week i was cleaning a couple of semi's, gutters & fascias, and because i didnt want to get my main window cleaning brush covered in ecover, i reached for an old 17ft extel i had in the van. i'd forgotten how bendy they were and made the job alot harder.
