Query: Operative word is "mini".

The compass works well but if you mount it on the dashboard you might need binoculars to read it. The picture on the website is quite misleading, as it is approximately twice as large as the actual product. It would have been useful to have the actual dimensions of the product included in the description. The compass ball is barely one inch in diameter, and the suction cup raises it a whopping 1/2 inch up in the air. The shipping rate of just under six dollars is another example of a hidden price. Save yourself six bucks and look for this item in a dollar store near you.
