Seems to work very nicely - can't vouch for accuracy but back ground radiation seems about right!

This geiger counter comes complete with Arduino NANO plus circuitry, pre-programmed so you just plug it in a 5V USB outlet and it's ready to measure! Just one thing: the glass tube and the holder size don't match (which is odd). I had to bend the holder's clips to secure the glass tube into place. It holds, but it's not sturdy and firm that way. Otherwise, great product! Last but not least: Banggood re-sent this delivery after my postal service messed up. Thanks a lot guys!
