For two and a half years I have been using the Sigma BC 1009 cycle computer on my bike which I mainly use for commuting. In that time it has worked flawlessly and only required 3 battery changes.
The device comes with instructions but they are fiddly to read so I created a YouTube video. I use it as a reference myself and it has proved quite popular among other BC 1009 owners.

I tend to find that the battery lasts between 6-12 months and as long as you change it when the battery warning comes on the settings are retained. That’s nice as it saves messing around with the wheel-size values.
I like the way it is really easy to remove from the bracket with a simple twist and is robust enough to have survived over two years of vibration, rain, mud and the occasional 1 metre drop onto concrete.
Here is the full specification :

The only thing I don’t like about it is the fact that it is assumed that users who want a 24hr clock would want the distance and speed values in Km. If you want your distances in Miles then you are forced to have an AM/PM style clock. A minor annoyance if like me you want distances in Miles and time in 24hr format.
