I bought this in anticipation of the onslaught of winter. and I have been lucky enough to test it out.
as a squeejie its brilliant, it knocks off water like a dream, the brush feels super soft and deep so should shift snow in a trice. (It hasnt snowed yet so I dont know how good it is/isn't for snow).
The long pole is plenty long enough to get all the way across any car bonnet... and perhaps most vans too... its enormous.
The ice scrapper though is a little bit flimsy... its hard to get enough pressure on it to really shift the ice... it does have a go, but for a high spec ice and snow shifter its not quite good enough. The problem comes from the long handle, which makes it harder to give it a solid push. You can detach either end and use the mini handle. but a big plus of having an ice scrapper on a pole is that it doesnt go all over your hands and fingers, which reverting to the hand scrapper you would be using something the same as a £1 scrapper from a garage.
