Using the SKLZ Premium Golf True Line Alignment Putting Mirror is simple. First, place the mirror on a flat surface of the practice green. Then, put the ball in the cutout. As you set up for your putt, use the alignment markers to position your head and eyes correctly. Keep an eye on the putter path lines to ensure a square takeback and follow - through. If you want, you can insert tees into the slots to create putt gates. This can add more challenge to your practice. When it comes to maintenance, just use a soft cloth to wipe the mirror clean after each use. Store it in your golf bag, but be careful not to crush it. Avoid exposing it to extreme heat or cold, as this might damage the mirror or affect its non - slip base. With proper use and care, this putting mirror will be a great help in improving your putting skills.
