I’m very impressed with the GQ GMC-500+ Geiger Counter. It works exactly as described and measures radiation levels with excellent accuracy. Now I finally understand the real background radiation level around me, and it’s surprising how easy it is to use — just turn it on and it starts monitoring instantly. I especially like that I can compare my readings with radiation maps from other locations, where people use the same model. This gives a much clearer picture of what’s going on not only around my home but also in other regions. The device feels solid, the screen is bright, the data logging is very helpful, and the battery lasts a long time. If you want a reliable radiation detector that actually shows real numbers — this is the one. Highly recommended!

Respect EU and FR charts conformity for the electronics materials and components 🤗 The system works really well! Fast delivery from uk to FR in under 24h times Thx to GQ Electronics LLC, your geiger device was great and work well

If you want a peace of mind you can't go wrong with this Geiger counter. I am very satisfied with the results. Get yourself one. It's worth the price you pay for it. I recommend you get a small case with foam in it for storage when not in use and to protect it from getting damaged.
