Seems to work ok .. but not sure just how accurate it is.
Anyhow, better than nothing and should give at least some basic information/warning should ever be needed.

This unit was bought for continuous background radiation logging and analysis.
It failed completely within 6 months - no display, battery fails to charge.
Waste of money

This thing detected some radiation from a radium lumed watch and went off the charts with more than 10,000CPM. Complete trash.

5.0 out of 5 stars Great for my use!
Reviewed in the United States on 19 December 2023

I love the sturdy build quality, rechargeable battery, and included diagram. I found the Geiger Counter to be easy to operate. I used it during my radioactive iodine treatment for thyroid cancer. I used the data to make a graph of how radioactive I was over time. I loved the price & quality compared to other Geiger Counters. The data I got was in line with my expectations give my dose of RAI (I-131), so I felt it was accurate enough for my nerdy purposes.

While I don't recommend thyroid cancer, I do recommend this Geiger counter!

Reviewed in Italy on 10 May 2024

Prodotto base per uso casalingo ma fa bene il suo lavoro. I dati sembrano abbastanza affidabili, ha diverse possibilità di personalizzazione dei dati e la batteria ricaricabile dura molto (se usi lo stand by) ed è facilmente accessibile nel caso si debba cambiare.
NON rileva le radiazioni alfa e purtroppo il software disponibile (logger e viewer) non va bene perché legge i dati da porta seriale mentre il cavo fornito è usb-c.

Walked around my town for an hour and a half in the evening accumulating about 20 millisieverts; delighted to know I don't live in Fallout and will be in the know if Putin or Xi go full Strangelove on us.
