Yeah i really do belive i have done the right thing with WFP, 95% plus of my jobs have come from word or mouth and that i do FRAMES as well, which is a real big big plus.
I am new at window cleaning and WFP, but by reading all the forums ( not just one )about with the information has help me a great deal.
Alot of my new customers love it as they dont have some dirty pervert looking though there bedroom windows, speaically when theres young children about. ( not saying window cleaners do this, it was comments from customers to me which ill share )
There the 2 massive plus points and alot of them love it due to them two points allow.
As for it being faster/slower i have no idea as i have not done windows the normal way and i dont no if its faster as i spend alot of time on the 1st clean. ( like someone said tell them your investing the time now as you hope there be customers for a very long time )
Anyway hope that helps in some way
