From reading the web page alone I couldnt work out what it was supposed to do.
Then I wondered if it was some form of knucle duster. However 4 things sprung to my mind when I finally understood what it does.
0.5 Sh!t I’ve never worried about this problem, will have to now.
1. Rubber band
2. It doesnt actually stop the car from getting scratched.
3. Whats wrong with the ground.
4. You will never make money unless their are lots of gullable people out there.
oh 5. Whats the compass thing for ?
Its a bit like spending £100’s of pounds for a seat post that drops when you can just undo a leaver that does the same thing.
