Review on 🌡️ WAYSEAR Professional Radiation Detector Dosimeters: Accurate Radiation Measurement Tools for Enhanced Safety by Brandon Plowden

Easy to use, nice bright color display and high sensitivity, but I cannot guarantee accuracy. The only problem is that the device I received didn't have a radiation alarm, which is a deal breaker. The rightmost button was supposed to control the sensitivity of the alarm, but on the one I got it only toggled the backlight. My photo shows him testing a Fiestaware mug and this button has a lightbulb icon instead of the thermometer (level alarm) shown in the seller's photos. I sent it back as it didn't have an alarm function. I tested the device with both AA alkaline batteries and with a USB connection, which showed very low power consumption, so even alkaline batteries should last a long time.
