If your looking for a company that can provide you with technical help on a product that they sold you, this is not the place to buy anything. But they will tell you how sorry they are.

Ordered on a Monday evening and arrived in New Zealand Friday afternoon. Very good prompt service and the compass was installed on the Saturday after calibration. Thanks Military Fasteners!
