The average radon level in your house over a week or month is meaningless when it can change so drastically month to month. With it on, a few windows cracked, and the central air intake in the basement sealed to increase relative pressure, I've managed to get radon averages from 5 pCi/L (dangerous) to 0.50 pCi/L (safe) regardless of the heater occasionally running."
"The Corentium and the SS were turned on at the same time and allowed to run until the SS started to show a result (due to the SS not showing an initial reading until a couple days after turning it on or resetting it, whereas the Corentium starts showing a reading almost immediately). Then I sealed up the charcoal tests and mailed them in and checked the readings of the Corentium and the SS which had now been on for 7-days (the reason for 7 days is that the devices both provide readings at 7 days but other readings are at different time parameters and so not comparable). Charcoal Test #1: <0.5 pCi/L. Charcoal Test #2: <0.6 pCi/L. Corentium 223: 0.97 pCi/L ("7 days" reading). Safety Siren: 1.2 pCi/L ("S"=7 days reading). Please note that I bought both the Corentium and the SS in March 2014 and so both were almost 2 years old at this point. I'm not sure the charcoal test results and those of the Corentium and the SS can be compared directly since their readings are over different times (approximate 4 days for the charcoal test vs 7 days for the two devices; I had to do this since the charcoal tests cannot be tested for more then 4 days and the two devices do not show readings at shorter times (e.g. 3 days, etc.). Interpreting the results is not exactly easy or maybe even valid, but it does at least seem to show that the devices are not wildly different than the charcoal readings and more importantly, they seem to read higher rather than lower than the charcoal readings (i.e. they do not give falsely low readings). ---. [Original Review: April 2014]. Just want to point out that this radon detector does not wait for a couple days to give an initial radon reading, like some detectors do (like the Safety Siren Pro Series3 Radon Gas Detector - HS71512 by Family Safety Products, Inc. does), so basically within a minute or so of turning this device on for the first time (or after resetting), you will start to get initial readings that are predictably around 0.00 pCi/L. Over the next couple days (again, the initial readings were after 2 days already), the Corentium reading starting to creep upwards, going from mid-0.5s to around 1.0 and then above, while the Safety Siren Pro stayed fairly steady around 1.7 Another couple days may bring the Corentium to around the reading of the Safety Siren Pro, which would make me feel better that they're both reliable if given enough time."
"Fast forward a few years, I did some minor basement renovations to remove batt insulation between the exterior rim joists and install a DIY spray foam seal, and replaced my window well windows with dual pane vinyl inserts. I bought the Corentium unit, because of the great reviews and easy continuous monitoring. I was surprised the Corentium reported high levels even in the upper floors of my house. I have loaned the unit to friends, family, and neighbors to help them make informed decisions."

"Very durable but not suitable for detecting or sampling low level ppms in the 0-30 ppm range."
"EXPENSIVE BUT REQUIRED WORKS GREAT."
We've spent a decade rejecting kegs made overseas because the interior welds have never met our standards. If a weld is not perfect and shows evident burn marks along with nooks and crannies it cannot be sanitized effectively. In and Out is etched near the keg posts for easy identification which is very handy when you are connecting lines in a refrigerator or kegerator and trying not to make a mistake.

"I had to replace the connection on the keg because they would get stuck and release beer/co2 when disconnected."
