Deflectors.

Just fitted a set of car window deflectors,  which is something we have never used before.  We tow with a Mitsubishi Shogun which has large front windows, and creates quite a draft for the front passenger when the drivers window is open.  In the summer I like the offside drivers window open a little,  but the downside is my wife gets all the draft around her neck. Does any of you use these and do you find they help or not,   the one's I have fitted are made by Heko.
