I know a few trad guys james and they swear blind its better and quicker but I just cant see it, trouble is they buy the kit and try it for a day and its not as quick cos takes time to learn how to be quick so they never go back to it. I had two guys come up to me when I was cleaning and ask me how I found it, they both had systems in the van but never used them. I did 1 and a half houses while they did one between them and they still didnt get it was quicker....
