I've spent hours searching Revain for reliable Geiger counters even though I knew absolutely nothing about them. I didn't want to spend hundreds of dollars. The first thing I would do is look at the negative reviews. If it said the device would never turn on, or its score was 10 points below the correct one, it went in the proverbial trash can! The only device that looked good was tested by those who seem to know what they're doing and only has 4 and 5 stars, which is a rarity for Revain! We got it in three days, set it up and checked the readings on the attached map to see how our house rated in different places. You could probably try food and drink and yourself at different times. We didn't use the WiFi option because it's really "boring" for us, but hey, nerds might be happy about that! I have recommended this particular device to some of my friends.
