Leaves a lot of spots for me
I have gone through a good portion of my first bottle of this product. In my experience, it does an ok job of not leaving any streaks but it isn't that effective in actually cleaning the windows. I typically use this after washing my car - I followed the directions and after applying the product, I finally buff it with a microfiber cloth. In my experience, I see a lot of left over spots after washing the car, that are visible when the sunlight hits it just right. For a product to receive high marks from me, it should be very easy to use and should just work. The effectiveness of this product for me has consistently been more miss than hit and till today, I have yet to figure out what I need to do to get the same results that others users rave about.
