Review on 🏌️ EyeLine Golf Putting Alignment Mirror, Portable Putting Trainer, 12 x 6-inch Mirror Size, Seen on PGA Tour, Made in USA. Ideal for Outdoor Use or Indoors on Putting Mats [SEO: Putting Alignment Mirror for Golf Practice, Portable Putting Trainer, 12x6 inches, PGA Tour-featured, USA-made, Suitable for Outdoor/Indoor Use] by Uriel Arocha

I bought this machine because I didn't feel comfortable with tripod putters. I've watched several videos on You Tube on how to practice with an eye alignment mirror. I took it to practice and set it up on a straight shot about three feet from the hole. The mirror tells you if your eyes are inside, just above, or above the line. Placing the tees just outside the width of the club in the mirror will help you determine if your path is correct. Once I got comfortable with my setup and shot, I came back about 6 feet without a mirror and threw 25 of 28 shots. I know that if I keep practicing with this mirror, my shot will improve and so will my handicap.
