I decided to give it a try because only the wholesale clubs have it and dealers are starting to offer it. No independents that I know have it. The Nitrofill program seemed like the least expensive and had the other selling points that came along with it. My investment was $500 plus the rental of cylinders. To answer your question there is not a big demand for it here at this point. They say that you must educate customers on its benefits. I also thought it would be good for vehicles with TPMS. I hear that in Florida where the company is from it is big. It is not easy to sell although the program with the Auto Club is a great deal for the consumer. I used it on all my personal vehicles and used the towing service on my wife's vehicle once. You really do not have much to lose if you go with Nitrofill.
