Review on 🔍 SOEKS EcoVisor F4 Geiger Counter Radiation Detector Dosimeter Nitrate Tester Electromagnetic Field EMF Device Water Quality TDS Meter Portable Electronic Touch Screen User-friendly by Alejandro Anaya

The battery only lasts a day with little use. Terrible. The radiation meter does not appear to be accurate. In the same place, restarting the device or resetting the counter will result in random readings. If it measured radiation it would be consistent. Also, during my initial testing, the device fell from about half a meter onto a hard surface. He landed on his back, but the screen shattered anyway. This is due to poor hardware and software design. The device is now bullshit with a small drop of just 2 feet. Buyers beware: Invest in another company's device and stay away.
