Miniature Geiger Counter was advertised as a real working Geiger counter, and it randomly clicks and supposedly is detecting radiation that it displays on its high resolution color display. There is only one problem... The manufacturer never installed a Geiger Tube or semiconductor radiation sensor. No matter how strong your radioactive source is, the readout continues with its slow random clicks and data display. We opened one up and its a complex SMD circuit but also no detection device and its probably configured so that one could not be added. Has type C charging cable and complete instructions. Its new in factory box and makes a great sophisticated "Geiger counter prop", however its fake and sold "as is" no return. In factory box with charging cord and seemingly legit instructions!
