Hi Lightning Boy!
Noticed your post on bike computers. I've had the same problem with the second one I purchased. I'm very pleased with it and it seems to be the exact same one that dealers sell for $30 or more. The reason I bought a second, the first had no back light. Anyways it worked very well, all the functions worked and I could see the display in the dark. But occasionally it would reset because of vibration, like I took the battery out. So I'm going to do without it until I can hard wire it with everything else. The link still works and price is still $9.99.
