Has anyone tried this ?

It is not a cleaning solution but is added to help well..... squeegee glide. It is also supposed to prevent evaporation of water on the window,which could be handy in summer.
 It`s not cheap at nearly a tenner for 473 ml. but I was wondering if anybody had any views on it .
