Review
This device is fabulous - just what I need for my night drives. I live at Chai Chee, and carparks may get pretty dark sometimes. Parking is now made easy and quickly by the detection of distance of my front/rear bumper to the kerb. The beep that goes off may sometimes be quite irritating, so I had turned down the volume in which it wouldn't bother me too much, but still alerts me. I've also installed it on my front bumper, so that during parallel parking, it wouldn't be so much of a chore to giraffe-neck to estimate the distance of my car to the kerb.

What I like
Gets most of the 'near distant' jobs done with less hassle.

What I do not like
May be expensive to most drivers since it would be quite unnecassary.
