Mhhh... if you like that stuff for the effect, OK.
But do not expect to get a return on investment from the fuel saved by not operating your wipers... the stuff is much too expensive for this to pay for itself.
I guess all these little things mentioned here only work because they are for free; the fuel saving effects are very low but add up. But if you spend money for such low savings, you are out of the box rather quickly, IMHO.
