I do not own the Desidario, yet. I have been using vapor systems exclusively for three years now and LOVE IT!! I own three systems and look to add the Desidario this summer. I suggest calling Kevin at KleenCar(888-302-3400). Let him know Doug from Detailz-Auto/Marine in Maine referred you to him. Kevin has written many articles in trade magazines and developed the recon program for BMW USA. Very well respected and very helpful. Kevin has a wealth of information and has never made me feel I was inconviencing him with my follow up questions. Last month I purchased the TR6 from him and I am very happy. I went with the TR6 because it is continious fill, which is important to us, since we do a large volume of vehicles. Good luck.
