Yes, the product box comes with 2 attachments that should fit any type of golf grip.  Use the clear attachment for oversize putter grips (Flat Cat, Jumbo, bigger Super Strokes, etc.), and use the black regular grip for any other type of grip.  You may have to work to stretch the attachment over the end of your grip a bit as the attachment should be snug with your grip; moistening the inside of the attachment will help slide it over the end of a tight grip.  A loose attachment will result in inaccurate metrics or actions not being detected by the sensor.
