While I consider Ewan's angle of looking at this interesting I'm not sure how things would pan out if I took his angle of viewing this matter to the "edge of the envelope". E.g. yesterday I was working along the back of four houses from an unsealed lane - the surface of which was cinder, mud, puddles, weeds, concrete and grit.
My hose led in this for up to 50 metres and my pole hose would occasionally drag in it too. Now I could have just let it lie, (no pun intended) put up and retracted my pole as necessary and viewed it as the supplier's responsibility to ensure that he had sold me a pole that was fit for that purpose.
Or I could take the sensible view and look after my tools to extend their life - which might involve a method for tidying my pole hose off the ground and a piece of towelling to run it through from time to time and especially when I reel it all away and drive to the next job.
In the same way as I would not drive much above walking pace along this potholed lane in my van for fear of damaging my suspension rather than fight it out with FIAT saying that I should be able to drive at 30 mph for that is what the legal speed limit was.
What you need in this game is common sense and the ability to distinguish between personal responsibility and the responsibility of suppliers and accept that there is a whole "grey area" in which a disagreement with a supplier is counter-productive if it can be avoided.
Mind you, being able to express views about the perceived weakness of certain items of equipment and have a manufacturer try to remedy those and provide those remedies free of charge is as rare as and far more welcome than rocking horse faeces IMO!
