Mandark Car Compass, Vehicle Compass Ball with Bottom Stick, Dash Mount Adjustible Auto Interior Accessories for Navigation Hiking Direction Guidance, Universal for SUV, Truck, RV

The compass is accurate in the open air, i.e., outside the vehicle and AWAY from the vehicle (or maybe any other metal areas). Inside one of my vehicles the compass always points North; in the other it always points South ---- go figure! Therefore, it is useless for its intended purpose. If you want this for use in the field or any other open area, it seems to work just fine.

Easy to in tall, and it works.j.

Performs as expected

Never did work properly. Always faced west no matter what direction I was driving in and no matter what position I put it in.

Good Compass, Does not work very well in vehicle.

Still deciding where to put this gadget. My latest idea was to attach it to the glass on the windshield but changes in temperature may affect the way it adheres to the surface. Time will tell. It's a fun little gadget that is helping us decipher which direction we are going and if it helps when the gps says : "Go East. on ___."

The red line is not where it belongs and cannot be moved without breaking it. Haven't returned because I think they are all this way. Poor quality control.Pretty much disappointed.

If this compass is near any metal it does not read accurately. It is cheap and you get what you pay for.
