See , Nath just likes to tinker round with stuff as do I , I think WFP has pretty much gone as far as it can go really , we have hot , we have leccy reels , not much more is needed or even required to clean a window , sure things can get lighter and they will , but you cant really get purer than pure , hotter than hot .
Suppliers will always sell the next must have gadget and certain w/c's will buy it regardless of if its needed or not .
I like to sit back and see the fuss , if i think i can benefit from it big time then dependant on price i will buy the real Mcoy , if too much i will make a similar item to the best of my capability if at all possible , hence why i wind in with a black and decker drill , £400 on a reel , no thanks matey
