It wont, pull on a hose or turn off a tap both nothing more than a preference, there are just a few on here who are too easily excited.
its still easier than messing around with a loop of hose taped to your pole.......just like hot water,xtreme poles,switching from 8mm to 6mm hose and electric reels....they all make the job easier and more productive.....
Nonsense I get nothing on the glass that needs hot water to remove and you said the same until you decided that an overpriced water heater would make a good status symbol, I could build an electric reel for about £50 which unlike yours would have a free wheel making it easier to pull the hose out (roll eyes) but again I just don't do enough reeling in to justify the faff.
I wont slag the Uni valve because it does the job but just like my tap on belt it has its plus and minus points, for me the tap wins and for others it wont.
The extreme pole is a great pole but for work at 22ft and under it wont make enough difference to justify the price.
I'm just surprised you didnt mention Vision as it was another one of your game changers. lol
