I've always used a chalk line or a string pulled tightly between two nails, but there are problems with both. I got an email from GolfersRx advertising a Laser aid. I've seen ads for lasers before, but the reviews weren't good, in fact they sucked. This one seems different. You guys who take the game and putting seriously, please look at the site and give me some feedback if you have experience with it or other laser aids.
