Hi there!

Does anyone have one of these? Has anyone taken it apart? I would very much like to know how the sensitivity slider works? Does it move the spring inside or something else?

I guess this is a bit random, and a bit off topic, but I'm jsut interested...

Thanks!

What is a bonus buddy? The Pedometer?

Yup indeedy, the pedometer

The motion of your walk moves the parts inside and then it counts the steps. If it is one where you have to measure your stride it will tell you also how far you walked.
