Gotta say i love my supalite, no matter what you lot say about them , its fantastic. I reach much more things than most window cleaners do round here, and som e of the local window cleaners pay me to come and do certain windows they cannot reach.
Admitedly its a bit of a pain getting all sections out etc etc but if your using it for a long period then its great. Odd window here and there is a pain. But like i say, all day use on big commercial jobs is fantastic!
Go for it!
