"Thanks for all the help in setting up my system. Everything works great with no leaks anywhere. The convenience of having multiple outlets in my workshop is fantastic. I have recommended Rapidair to all my friends. Thanks again!" - John

"I apologize for the delay in responding, but wow, what a pleasant surprise to get an email from a real person about my order! I'm so used to automated emails with "do not reply" in them I had to read this one twice! It makes me that much more confident in my purchase from Engineered Specialties, which I am eagerly awaiting delivery on. I look forward to doing business with your company in the near future. Thanks for the personal touch!" - Matt

"Just received parts ordered for my compressed air system. All parts are quality made and I am very happy with them. Thank you so very much for being so helpful and above all you were so very nice. Thanks again Stacy!" - Phillip

"Thanks so much for your help and fast response! I have been thrilled with all the folks I've had the pleasure to deal with at Engineered Specialties. Rest assured I will spread the word to all my fellow wood workers/friends who may need of your products!" - Joe

"Thank you for your concern. I can't say that any other company actually took the time to do what you have and reviewed my online order. I am so used to automated messages." - Wesley

"For what it is worth, I replaced a combination of PVC/Iron pipe. I could not believe how filthy, rusty and dirty the insides of the iron pipe were. They had only been up about 2 years and used very little. I am so glad I made the switch to Maxline. From all I have seen your product is a winner and so are the people I've had the pleasure to deal with thus far. I look forward to future orders from Engineered Specialties.
PS..I love your Bible verse!" - Mark
