Stem compass

Good idea but doesn't work if you have any asserory with a battery nearby.

Didn't work

The compass was easy to install, but once installed only points North. I don't know if the interference was because of the steel frame or the magnet for the computer.

Since I live in the Desert Southwest and ride in triple-digit temperatures regularly, I really like this. I was a bit intimidated, so hired the bicycle shop to install it. I liked it so much that i bought two (one each for touring bicycles.) The display is clear, and, so far, I haven't had any problems with the product.

Look, no batt's!
