Geiger Counter, Nuclear Radiation Detector

As someone who's pretty good with gadgets, I found this detector to be a mixed bag. It does its job detecting radiation, which is what I needed, but it's not without flaws. The heat issue is a big downside—it gets warm fast and that's not ideal for longer use. The alarms are effective but overly aggressive; I had to turn them off sometimes because they were too much. The display is clear, but navigating the different measurement options isn't smooth. I bought this mostly out of curiosity and for safety around the city, but it feels more like a basic tool than something high-end. It's functional, but I'm not extremely happy with it. Probably okay for occasional use, but not for daily reliance. 😕
- Pros: I really liked how small and easy to carry it is, fitting right in my pocket for quick checks. The screen is clear and simple to read, no trouble at all. It picks up different types of radiation well, which is handy for peace of mind. The alerts are extremely loud and noticeable with beeps, lights, and vibrations—you can't miss them. The battery lasts a long time, most likely through a full day of use, which is great for on-the-go.
- Cons: It runs hot after a while, which is annoying and makes it uncomfortable to hold. The alarms are way too persistent and can be jarring, almost like they're shouting non-stop. There are multiple ways to measure things, but it feels a bit confusing and not very intuitive to switch between them. For the price, I expected something a bit more refined and less clunky in design.
