KOKITEA Magnetic Window Cleaner for Double Glazing (Thickness of Glass 4-38mm)

My windows are triple glazed, so at the upper end of the 4-38mm thickness suggested, but the magnet did not seem to be strong enough so it kept falling from the window as soon as it moved. Would probably be ok for windows with a smaller glass thickness.

Do not buy if you have sash windows - It is tricky to place /position the 1st side onto the exterior facing window, then magnetise the 2nd side to it to clean the top and bottom of the windows. The 'English Manual' enclosed is a piece of paper with basic instruction in bad English - not helpful at all.Maybe it would be good in the hands of a professional window cleaner, but I am not impressed with it and wish I could return it. Way to expensive for no result in clean, streak free windows.I repeat, not good for sash windows and difficult to manoeuvre.

Works great on double glazing if you buy the right thickness. My windows are double glazed and very thick so i bought the most expensive one 4-38mm. Works great as long as you go slow. People that are writing bad reviews have only bought the 4-22mm which is not good enough for double glazing.
