    Item came as described, relatively quick and came wrapped in several layers. Worth what a vintage geiger counter belt from the 80's would go for.

    Good seller the SBM-20 sensor is original. My only gripe is the box and packaging were not ideal. Maybe use professional boxes and bubble wrap instead of random boxes.
