i started using mine the other day. like others have said does seem to require a very light touch. the spring loaded part is the most unusual, if i have the setting too soft then it seems to zero out, if that's the right way to describe it, when this happens it just smears the window, i.e., the edge of the blade just rides up over the solution(it was a hot day with full sun and i was using a soft blade so perhaps this may contributed). once i got the pressure about right it was ok. glad someone else pointed out about the light touch needed because i thought i was losing my touch and kept sticking more fairy into bucket as couldn't get it to glide until towards the end of the day, then it all came together. its just a pity it doesn't accept the super channels, if it did then it could make a good alternative to the sorbo and we can ettore stuff anywhere really in the uk, where as sorbo stuff is more web based. also i like the fact that you can set the horizontal angle with either a pole or by one hand just by a bit of pressure against glass/ sill etc overall a universal squeegee, helpful i hope
cheers
