Number one - so small and and so poorly lighted that you cannot see it at all. You will not be able to use it in cars where the mirror is longer distance from the windshield that the cable of the compass. In my Honda Element you would need longer...

This compass works ok, however, I had to calibrate it 3 times already. The down size, it that it does not stay on all the time, so you literally have to push the button every 10 minutes and even though it comes with a back light, it is not bright...

I was not satisfied. It is nearly impossible to read when mounted on the rearview mirror when the sun is out. Additionally, after four callibrations it still declares the Pacific Ocean is east.

The concept is great and there are many good ideas, but the size of the display is so small that you need a navigator to read the heading to you lest you run off the road trying to read it.

I probably went through 5 different "suction cup" mounted compasses and none of them worked properly. There are too many magnetic fields in a vehicle for them to work properly without calibration. This compass however worked great within 5 minutes....

If mounted and calibrated correctly it works fine. I just bought this because I didn't really want to spend the money (or worry about theft) of a GPS unit. Mine has a nice electroluminescent blue light when traveling in the dark, although it only stays...

Follow the directions and it works. The sensor seems like it must be in a level position to be accurate and that is how the instructions say to install it. Luckily its adjustable if you need to do so. In everyday driving it functions just as most...

The overall service of ordering, delivery and return was excellent. The product was the problem as it was defective. The return was easy and refund was prompt.

It was cheap so I figured what they hey, bad idea. It only worked when it wanted to, showed the wrong direction most of the time, and being cheaply made, fell apart.
