~Mark H., Michigan

“I can’t think of any suggestions for improvement. The Customer Service personnel are very friendly and very helpful and efficient. The plant really likes the product and the pricing is very competitive. Please always keep a customer service group that one can call and place orders with. Don’t go to all computerized like some larger companies are doing: more mechanical than interactive with no personal touch. Business should be about relationships. That’s the glue. Some companies make it almost impossible to talk with a live person.”

~Charlotte W., Oklahoma
