I needed a visual signal when entering garage. I like the brightness and power source (no batteries) Not perfect but works for me. Bought two.

Works great...

Easy to install. Works really well. Excellent quality for the price.

Not very precise for what I wanted, which is a little diffeerent than what it is advertised for.

It does not work, because it is impossible to adjust the distance.

This is good but anyone could tamper the adjustment. Try to improve it with a lock setting.

A very nice compact item.

I bumped into the front wall of the garage more than once before I finally realized that this device is not trustworthy. In order for the light to come on, the car has to be moving at a speed faster than I am comfortable with when pulling into the garage.However, installation and operation are fairly simple.

It worked well and arrived the day you said it would. Thanks

What do you get for the person who has everything? This was a present for my dad, who had a whiffle ball hanging to let him know where the car was pulled in enough to close the garage door. This item fit the bill admirably - not so high tech that he couldn't install it (he doesn't really do well with computers and the like) and it worked well, although setting the exact distance so that the light comes on at the right place is a little challenging. It made Dad happy, so it worked for me.
