Customer Rating:      Summary: A Nice Little Unit! Comment: I hope this short reveiew helps others, like the prior ones I read right here on Amazon did for me. This is a nice little unit; it does exactly what I wanted it for. I recently purchased a newer car, my older vehicle had too many gadgets to suit me. I never used three-quarters of the stuff. But the one thing I did like was the compass in the rear-view mirror; hence my purchasing this battery operated compass. A couple of things of note: It said in the instructions that you would need to (ideally) find a large parking lot or space, to basically drive in circles to calibrate. I did that and it still didn't calibrate. So, I thought, since I have wasted almost 15 minutes on this action, I'll do it at another time. But, then, on my way to the grocery store, wham, it calibrated itself. It was easier then the instructions led on. All positives from this end. Not obstuctive sitting on the dash. The sticking unit for the base holds it down really good. The ONLY thing I wish is (that is why I didn't give 5 stars), that the little light that goes on for a couple of seconds when you press it, would stay on longer, or maybe constantly when pressed once. Then shut off when pressed again. Otherwise, I don't think you will be disappointed in your purchase.
Customer Rating:      Summary: big compass for a little car Comment: We own a small coupe and the compass is too big for the dash and doesn't articulate enough to get it to hang off the visor. It also has chrome trim that reflects. I can't find a place to anchor it so that it is readable. It does fit down by the gearshift but there it's not easily visable and the plastic facia doesn't allow clear seeing when I wear the polarized sunglasses. It does appear to be accurate. It comes with double sided velcro to attach to the dash - not on my new car!
Customer Rating:      Summary: Type S digital automobile compass Comment: Even though I have a portable Garmin Nuvi 660 GPS system, which works very well, I find I often need to know in exactly which direction I am headed, e.g., when the Nuvi says, "Go north to ..." I had purchased one of these compasses for one of my vehicles, and decided to buy one for the other.
I have found that it works very well, once it is calibrated, unless the batteries vibrate loose. It was very difficult for me to figure out how to open the battery compartment, since they provide no understandable instructions, but very easy to do so once I figured it out. I wish the backlight would stay on longer after being turned on. I find it interesting to see how much the direction shown changes before and after calibration, i.e., after it has adjusted for the car's magnetic field with the engine running.
Customer Rating:      Summary: nice compass! Comment: It looks nice, it works good and accurate. Has a lightning button which lasts for a few seconds at night, and an auto-turn off feature. Warns when batteries run on low, however can run for a rather long time after it.

Seems to work well. Will need a couple of months to check it out.
