(4 stars) - Good alternative to consider vs. test kits
We have used test kits in the past, including the "snapshot" canister test Realtors use that samples only for a few days, and the longer-term alpha-track test (3- to 6-months sampling). We've noticed that radon increases dramatically if our radon exhaust fan is broken, returns to acceptable levels when it's replaced. This time around, I got this instrument so we can keep an eye on radon for a long time without having to get many kits. It seems to work well, readings are consistent with past tests (albeit years ago) with the exhaust fan in good shape. Radon does vary over time and for many reasons, so I like having both short-term (7-day rolling average) and long-term (cumulative average) readings.

I do wonder about accuracy. I see some reviews where folks have apparently compared it to test kits and found it accurate, which is a good practice and reassuring. However, I see some folks who cheerfully assume that the meter is "more accurate" because it gives them much lower readings than test kits did. Sorry, but as Confucious say, "Man with two wrist-watches not know what time it is." If both conventional kits and the meter agree, I'd feel good, but if they vary a lot as some reviews indicate, there's no way to tell which is correct and the last thing I'd do is cheerfully assume on the happy side, one might be missing a serious problem. But, so far, it seems "in the ball park" that I'd expect for our home. I may get a test kit and challenge it, but I don't think we have a problem so the incentive is low compared to folks who may have a problem and should be more rigorous or cautious.

In summary, I think it's a good alternative and certainly good for monitoring directional changes, but if there was any reason to think there was or might be a radon issue, I'd get a test kit either in addition to or in lieu of this. Also, keep in mind that in many places, to sell your home you need to have a radon test run. I am almost certain that this instrument would not be recognized (whether it should be or not), and it would be bad to assume things were good due to low instrument readings and then find that the Realtor's test shows a problem you have to fix before selling, so as a practical matter, one should get a recognized kit if planning on selling.

(1 stars) - NOT EPA approved for real estate transactions
NOT EPA approved for real estate transactions. They tell you it was EPA evaluated.....So? I can evaluate anything...LOL. Even charcoal canisters (11 bucks) are approved for real estate transactions...........very misleading in my opinion

(4 stars) - Seems to work
It seems to work, but one concern I have is how accurate the "average" level is. My home has high radon levels when the water table is rising. This happens over a few weeks in the spring. When I first started my detector, radon was high, ~10-12 for the first week. It then returned to ~4 for the next week. At the end of the second week, the "average" was in the fives. I would think that one week at 10 and one week at 4 would average 7 for the two weeks. Perhaps I missed some really low readings, as I checked it probably twice per day.
I have not tested my detector against a certified monitor yet, but I plan to next spring when I have my radon remediation company come back out and work on the peak levels when it rains.

(5 stars) - Works good
I bought the Safety Siren Pro 3 as a way to test radon levels in real estate transactions. I've tested my own home several times with the charcoal canister test kits and found the Safety Siren provided results that were very similar to the canister results, except you get the results faster. The device is easy to use and has worked without a problem through 3 short term tests.

(5 stars) - Worth getting
We have the version II of this and found it to be accurate and useful. We confirmed the results of this device with a professional tester and also a series of 3 day and 3 month charcoal tests....every single testing method we used matched the digital readings on the Safety Siren II. Cant speak to the III version, but they at least look similar in appearance. Given the substantial risk of radon, this is for sure worth the money. I still do charcoal/carbon tests every few years to verify as well.
