Cleaning Kit

Windex outdoor all-in-one glass cleaning kit; does it really work?

I would like to purchase it but I am hesitant as I think it will leave streaks. Comments/reviews please.
I have coupons

The reviews on Amazon.com are mixed, so it is hard to say. Depending on how much off your coupon is, it might be worth a shot. It looks like a Swiffer for windows, it could be lots of fun.
