Negative Positive
Title: Value and peace of mind for a good price
Review: Needed something that could verify presence and ... even better the absence of radiation. Wasn't expecting a lot but this device works as stated, i.e. readings between 0 and 9.99 (Max for device). Was able to compare values that were close enough for a consumer who just wants to ensure a clean environment. Suggestions: (1) batteries are best inserted 'nub-first'/positive-end-first AND snug against the middle otherwise it tends to pop out (2) possible places to check the device are in a hospital where people have received radiation treatment (found this out inadvertently) or near an x-ray machine that is used to scan bags (office building). The digital reading lags the audio which is pretty quick, i.e. registers each particle as a beep or rapid-beeps.
