Thanks for the follow up. I had the converter installed a couple of days after I received it. The install went very well. The electrician had never used your products before and was very impressed. I also was very impressed with the entire experience, just to take a minute to explain my view point. I run a very large Tool and Die manufacturing company here in Detroit,  this purchase was for my personal shop, I primarily restore Vintage motorcycles and minibikes.


So the short of it is I deal with a lot of companies large and small for both of my businesses and dealing with you guys was a pleasurable experience.


You guys really have a great team from everything I can see, as you may notice I love  to analyze business and American Rotary is a very good one.
