Updated Golf Putter Aiming Device for Perfect Alignment Tool, Golf Putting Aid Portable Practice Putting Trainer Aid for Indoor & Outdoor Garden Backyard Use

this is pretty amazing , especially for the price, after pulling out the plastic tab from the battery, you can turn it on by pressing the button, the laser is bright red, very bright and sharp. there is a tab for two settings on the light, but i don't know what the difference is.

Very poor laser.Can not see it in the day time,only when its dark can you see the line.The unit only will stay on for 5 seconds and then turns off.No instructions come with the unit.

Works well in the evening when dark. Day time does not work.

Does what it should. The laser helps align putter to target. I use it with my putting mat and on the practice green at the course and it has helped make sure my putter is lined up correctly each time. It’s helped improve my putting game
