Sensitivity awful
I have used a Russian Geiger Counter for years so thought an upgrade was in order. Testing with some gas mantles still showed a clear indication from a couple of feet away with my old Russian model, this one had to be held almost touching them. Same with radium glass, watch hands etc. etc. Returned same day.

Great for money
