Richard - i have used the vikan for around 18 months - and it's not the best bit of kit ever invented.results can be hit and miss on 1st cleans requiring glass to be cleaned twice, i use white vinegar on the padsas i found using pure smears the dirt with streaky resultIt's great for regular cleans where you cant normally reach without a ladder/steps i always change the pad every 3 to 4 windows/ glass panels otherwise they smear. they take a bitof getting used to as regards using as they dont glide over the glass too well, but once you have the knack it's all ok.Darran
