Special Reminder:
You should confirm the correct direction outside the car before finding a suitable location inside the car. Avoid iron and magnetic items in the car from affecting the ball compass reading.
- Features: mini size, shockproof, waterproof, accurate pointing
- The reading method of ball compass is opposite to the pointer compass, the direction of the ball compass you see is the direction the car is heading.
- Installation instructions: First determine the correct direction outside the car, other reference compass should be separated from the ball compass by more than 20 inch.
- Then find a suitable position in the car so that the direction of the ball compass is the same as that outside the car.
- Finally, tear off the double-sided tape to fix the ball compass.

It works fine but is much smaller than expected

For an inexpensive plastic compass with no adjustment ability, this is not bad. Ball floats easily, numbers are properly aligned so you can read the course from behind the compass, not overly sensitive to local disturbances.

It’s a good product just somewhat smaller than I expected.

Looks like it’s pretty accurate at least sitting on my coffee table. Gonna install and see how it works soon. Will update as time progresses. But its exactly what I was looking for as far as size and readability. I give 5 stars for now. May adjust later

bought this for my 2021 honda pilot. sad to say but all place on the dashboard this compass will have magnetic interference so it’s no good! luckily it’s ok on my wife’s 2016 subaru outback.

Too bad I did not read the description, but it is too small, smaller than a golf ball

Unfortunately I couldn’t find a single spot in my truck where it wasn’t being influenced by metal. Works great as a compass outside of the truck. The second I bring it inside it just finds metal anywhere and points to it. Not even holding it up dead center in the air made it read correctly. Again, It does work as a compass, but I could not get it to work inside the truck.
