Review on SwiftJet Foam Gun Sprayer with Wash Mitt - Adjustable Water Pressure & Soap Ratio Dial - Garden Hose Foam Cannon (Blue) by Leo Puente

Great product, I was confused by the little black label too, but it's for insecticide or fertilizer spray rather than washing the car. One more thing, when you're done foaming and washing your car, remove the foam nozzle and rinse it out. Then a powerful jet of water comes out of the water. I'm glad I realized this isn't explained and yes the instructions are too small to read.
