Truly effective, a few hours charging time before first use. Allows enough net work (at least broadly as well as if it was his glass in hand: there is still residual traces). With some application there are very few defects and especially weather gain !!! We can, if we want to invest in a handle adapted to Leifheit system to work more in height. Unlike the better known German competitor can also do its roof windows, appreciated! A fault if we must note one: the squeegee is very wide making it necessary to make narrow windows laterally, perhaps could have been designed a replaceable scraper.
