the entire caliper, including the caliper and cam, all plastic. So I believe they are good for ear measurements and also consider them "thrown away" if the battery is installed and an extra battery. I assume it has an extra battery because they can easily stay on and drain the battery. Considering the view, they're definitely less than $10. So what to expect?
