I was given MrCCW as a gift, I wouldnt have purchased it myself as I actually like cleaning my car and, well, I had my doubts going in to it.
At first I really enjoyed the lack of drying time, very convenient.
But I hated the sprayer! Holding, wrestling with it as well as the hose...then trying to set it down to physically wash the car. The thing is like a ******* iron that doesnt wanna stay upright. I also found the knob annoying...but not as bad as the over all design of the sprayer. Imagine washing your car with an iron...and it feels really stupid using it(what will the neighbors think?)
But my biggest complaint is the soap, its extremely sticky! I made the mistake of storing the bottle sideways(by accident) this left a sticky gelatinous goop. When using this soap in a bucket its stickiness becomes more obvious on your arms...and once the vehicle is clean(and dry), I find the car is sticky/tacky all over...this cant be good for keeping a car clean!
After replacing the filter and the soap once I gave up and went back to my normal routine...I gave the MrCCW to my mother who also has a car cleaning compulsion and could use the relief from drying...also I value her opinion on automotive cleaning products...but I dont believe shes using it anymore either.
