I bought it after I posted about it in the old forum. I liked it for when I just wanted a quick clean, but with all that goes on I usually can't wash my car till late evening, then it just doesn't dry at all in the dark. So for now I've gone back to washing and drying normally.
Plus after first use I stored it back in the box, and the soap leaked of the unit.
David, did you change the filter after those first three washes? Three washes is what I've heard the first filter is good for and that's it. The life of the filter depends on how bad your water is of course.
