Dont waste your money. Have tested it already(got a free kit to sample), and it does not work as it states. The sprayer is decent, the car soap does not sud at all, and the final rinse is like a water pistol. You still get some spots with the mr clean thingie, and it just doesnt magically sheet off the car as advertised. You are better off using an inline water filter, or just use the classic method of taking the nozzle off to let the water flow off the car, then use your california water blade and a waffle weave microfiber towel to dry.
