Geiger Counter, FELLAT Nuclear Radiation Detector, Portable Digital Dosimeter High Sensitivity Beta Gamma X-ray Radiation Monitor with Large LCD Display

Unfortunately, whilst the first device sent from the warehouse powered on, the screen didn't work. After contacting the supplier a replacement was quickly sent that did work. Good customer service.

The operating instructions are iffy and the click noise is very low and not load enough

Works - reasonable size - display ok BUT battery life about a week - on my second set using quality alkaline cells - so of no practical use - sad to say

Does not work at all, no different when you put it next to a microwave or iPhone or electrical devices . I have had different counters before and worked okay but this doesn’t change at all. A waste of money

Could be very useful one day. I hope that day doesn't come when we will need it.
