All Evnroll putters are made in the USA and feature patent pending Sweet Face technology. Sweet Face Technology causes the ball to roll virtually the same distance from center and off-center hits for unprecedented accuracy. Each putter design has two small, unpainted dots on the top line of the putter to give the golfer a subtle alignment reference for consistent lie angle positioning. The dots also assist the golfer on aligning breaking putts. Evnroll putters have lighter swing weight for distance control and more overall weight for greater stability and accuracy for short putts. The ER5 Hatchback model has a winged mallet designed with a hatched out center section.
