Once the light is calibrated to your chosen spot on the windshield, dashboard, or her eyes, parking is easy-peasy. The lasers are bright and easily visible as they hit the dashboard.

Product works just fine! My only complaint is this. It's a tight fight, but this device is perfect. It works as advertised.

This solves a problem i have been dealing with for a while. We have a small, 2 car under garage with a lollicolumn. If the cars are parked perfectly, everything is great. This beats the old tennis ball hanging down.

Bought this seven months ago and at first all was fine.

Instead of a focused red dot, it provides a fuzzy dull line. The range of pivot for the laser is limited.

Laser pointers can't be mounted between two cars. Did not reliably detect my vehicle when entering the garage. Laser is on for just 10 to 11 sec the most. The motion sensor is good for 8 feet.
