I just talked to my brother about this last night. He loves his, but then again he's not as anal about the appearance of his vehicles as I am. I'm not sure I'd want to use their soap (I use Meguiars Gold Class) but the de-ionizing filter is interesting. We have heavily treated water in my area due to a Cryptosporidium contamination back in the '90's. If I don't frantically try to dry the car after washing it will develop spots very quickly. I'm going to try and borrow his to see how it does.
