I want to take the time to personally thank you for your service to a customer above and beyond the call of duty. If you recall, I brought an Aerox cylinder by your booth the last day of the Oshkosh show with a stuck open relief valve. To my surprise, you immediately replaced the entire regulator with one you had on hand! This type of concern for the customer is a rare and gratifying treat. You can be assured that I will only use Aerox products for my airplanes and will encourage others to do the same. You guys are a class act.
