that's most likely because they mounted it on, or too close to ferrous or nickle metals, or too close to batteries (from a bike headlight or cellphone, or some other electrical device). Fits snug on bars.

I've found them both to be accurate and convenient. Here to dispel some of the bad reviews for this compass. & as the picture shows, it is just as accurate. Swapping steel bolts out with titanium bolts will solve this.

I took a chance on this little compass & compared it to my Cammenga H3. It is a perfect, general direction compass, for quick reference while bike riding, or hiking. hence the 5 stars. but this clip-on could work in a pintch.

Now as far as the reviewers claiming the compass just spins. ALL compasses only point in 1 direction, which is Magnetic North. This little compass and its companion thermometer fit perfectly on the aluminum mirror posts of my ICE Adventure HD recumbent tricycle (see photo).

Those claiming it only points in one direction. Took it down some jump trails & it holds on solid. I clipped this on to my mountain bike handle bars, & it maintains the same accuracy. .
I also own a Sunnto M-3G which also agrees with the Sun clip-on compass. Edit. I still prefer to use my Sunnto or Cammenga for land navigation, as they are better suited for use with maps.
