Convienent storage, carry it with you in your Golf Bag 
The single most effective tool to learn how to use an open stance setup,  with an open club face for more bounce and  more loft, for better  bunker play and chipping, to enable a higher ball flight and  achieve an acccurate ball flight to the pin.
Set up a putting configuration with an aiming rod, foot, hips and shoulders alignment guide rod, and a ball alignment guide rod that also serves as a putting gait. That refines the distance to stand from the ball, and how to hit the center of the putter face for consitant putting distance. This setup works precisely whether you have a straight back - straight through, or an arced stroke.
Set up a guide rod for foot placement in your stance for how far forward (towards the target) you place your foot relative to the ball placement, to learn accurate and  consistant foot placement. 
you can set a Foot alignment guide rod at any angle you want (open or closed stance), and another, seperate  guide rod as a Target alignment guide rod.
Set a Downswing path alignment guide rod.
An alignment hole is precisely drilled in the top and the bottom halves that enables using a golf tee or a short alignment guide rod to be inserted that lines up the Golf Puck for easy 90 degree alignment of the Ball Alignment and Foot Alignment guide rods.
