Would they buy this item again? Yes
Holy smokes! I put 20ml (less than a full dose) into a gallon jug of nothing but tap water and filled up my empty washer fluid reservoir. On the first squirt the window completely disappeared. I use Stoners Invisible Glass and exactly the same result I got from p21s as a washer fluid in nothing but water. I did notice that the squirts were sudsy, and the remnants on the wiper fringe did dry in place. However, I read about white residue complaints so that's why I only used 20ml in a gallon. I would say it's possible to use even less and still have great results with less suds. But overall, I cannot live without this!

This stuff WORKS! Absolutely the best thing to add to your washer fluid if you get a lot of bugs or road grime, as it boosts the effectiveness of your washer fluid a LOT. A little goes a long way too, so no need to add more than recommended.
