I purchased my unit last year and Im amazed at how it has changed my life. Jon and his crew are top notch. I was very excited to get mine in the mail. It was delivered in perfect condition. It looked just like the piece of art it is. The fit and finish showed great attention to detail. It was not just thrown together. I could see the pride Jon and his crew put into the production of this all American still. As a Veteran I really appreciate that! As for the operation, it works flawlessly! I have run it all year long with no problems what so ever! I have recommended TDN www.TheDistilleryNetwork.com to everyone. This unit will last a lifetime. I have a 6gl. unit and will be getting a 20 next! Maybe another 6 to pass down the knowledge and art to my grandsons! I will tell you this It will be from Jon at TDN!
