Missy Craig (Murmac Farms, Bellefonte, PA) said, "We mil 650 Holsteins here in Pennsylvania. We began using the Thrifty Dippers over a year ago ... We have had a great experience with the Thrifty Dippers! They pay for themselves very quickly and have a money-back guarantee. It may interest you that Mr. Hakes is a retired dairyman, and the entire idea for the dippers came from his own frustration with watching teat dip get washed down the drain after milking."
