Review on Ultimate SwiftJet Garden Hose Foam Gun Sprayer Set with Microfiber Wash Mit - Adjustable Water Pressure & Soap Ratio Dial - Attaches to Any Hose for Premium Car Wash - Foam Sprayer with Wash Mit by Josue Zepeda

This product costs around $8-12. The most expensive components are brass and tin fittings. However, it's no better than a soap-filled Walmart/Tractor Supply chemical sprayer (although it's rated for chemicals like rounding or fertilizer). That's right. You can easily find a "soap" tube dispenser at large stores for around $20. You won't get fast connections, but it's still not too expensive. You will get the same results if you spray soap through them as you would with this item (the Bernoulli effect is not patentable). This item is a simple water siphon. Spend your money elsewhere.
