Is it O.K. to leave the green outside? This Putting Green is only for indoor. Is the green hard to assemble? In most cases a any green can be built in 15 minutes or less with only a Phillips screwdriver. Larger greens will take a little bit more time but still less than hitting a large bucket of balls on the driving range. Once I have built the green can I move it to a different location? Simply take the green apart and re-install it at a new location of your choice. Can you change the contours? Yes. By inserting the foam contour mats under the turf, an infinite number of breaks can be created and easily changed. Why do the cups move? The cups are designed to move to allow for the expansion and contraction of both the platforms and the turf thus allowing for perfect cup alignment in all weather conditions. Can I expand the green once I have purchased a particular model? Simply purchase additional panels and a new piece of turf and a new design can be created. Is the turf fast? The Tour Links putting turf is designed to replicate Tour speed conditions. What if my backyard is not flat? No problem. Once locked together the panels are designed to flow smoothly over uneven terrain. Do the Tour LInks greens come with a warrenty? All Tour Links products are warrented for 3 years against manufacturers defects.
