Negative Positive
Title: Save your money
Review: We bought the monitor earlier this year and followed all the instructions. We tested our basement where we usually test with the carbon tests, then we tested on the upper two levels. The results were about the same on all 3 floors which shouldn't be right. Out of curiosity, I opened the window near it for several days and the value never changed. I ended up calling several radon mitigation companies and the state lab. Everyone told me to use a carbon test and not to trust the cheaper continuous monitors. They said that they do not keep their calibration. After running 2 repeat radon carbon tests, I see that the monitor wasn't even close. Save your money and time, and don't buy this monitor.
