Title: Turn your brown spots florescent green!
Review: I certainly like the idea of this product, and the word "instant" had me excited, but it works exactly as well as spraying your yard with food coloring. Yes, it makes the yellow spots green. But unfortunately it's not a shade of green found in nature. The startlingly bright green spots won't bug you for long, however, because once the stuff absorbs into the dead grass, it turns back to being brown within a couple of hours. Not sure if it actually corrects the PH of the ground. I'd think just a good rainfall or watering would dilute the urine enough. If you follow the dog around with the sprayer, it may work phenomenally.
