Been using it for a week on my route. Virtually no film, plenty of slip even on hydrophobic glass, no bleed, good suds like Fairy or Dawn, leaves a perfect clean with a brilliant shine. I tested it on my most problematic windows for filming. Not cheap however. But personally I like pricey toys and tools. There is no competition with this product. It is ten times more concentrated than products like Dawn. I put one quick squirt in a two gallon bucket then I just keep refilling with water all day.
