Love it, great peace of mind device to have. I really like the data logging feature. About the only thing that's a little annoying about it, is having to constantly reconnect after you leave blue-tooth range. I would have preferred a wifi version. The app leave a little to be desired. I feel like the data features could be a lot better than they are. I experienced a glitch in the data early on when we owned it that I think might have been caused by a power outage at the house. Overall satisfied with it even though there is room for improvement.

Moved to a new home in Northern Utah and decided I should get up to speed on Radon and wanted something that would give me real time data so I could see what actions affect my readings and the RadonEye has not disappointed. The only, and I mean ONLY critique I have is that there should be a way to silence the “beep” that reports when you connect to it via Bluetooth. My boys have their rooms in the basement and I’m monitoring levels mostly because of their exposure time being so great and I like to check in on it late at night before I go to bed but when they are already in bed and it can get their attention when a beep rings forth in the otherwise silence!

I bought this unit because we were finishing our basement and my kids were going to be spending a lot of time down there. I wanted to see what the radon levels were. Set up was easy peasy and it seems to work great! It samples every 10 minutes and plots the values out on a chart. It also tracks peak value, 30-day average, and 1-day average. It showed that the radon values in my basement weren't considered drastically "unsafe" per US standards (over 4.0 pcl), but it was higher than what I was comfortable with so I had a company come and install a radon mitigation system. After that, the unit immediately started reading much lower levels which was great for my peace of mind. Overall, seems like a great product which I have recommended a few times to others. Way better than those one-time, set it out then mail it in tests that only show one reading. If you want to know exactly what your radon levels are at any given time, buy it!

very easy to install and connect to phone, love the app which can show history data. I did a lab test to confirm the reading and they match very well. never have to worry about radon anymore

Our home has a radon mitigation system in the basement, most homes in our area do, so no big deal. We haven’t used our basement for more than storage for almost 11 years. Now that we have two very active boys it’s great to send them to the basement to play. However radon terrifies me so I did some research on a radon detector and decided this one was the most straightforward for me and did not really see calibration issues in the reviews. When the unit arrives, I immediately set it up. Half expecting a green, low number I was shocked to see our pCi/l in the high 4s. Then it just kept climbing to 5.24! I sent my husband a text and screenshot. He immediately went to inspect the radon mitigation unit and pressure indicator. The system had somehow turned off! He was able to turn it back on and see the radon mitigation systems pressure indicators zero out (a good thing that it’s working). We need to repair the switch for the radon mitigation system so it remains in the on position. But the peace of mind and additional, easy to check monitoring this device gives me was worth every penny!

I use this device to continuously monitor radon in a house with significant radon risk. Most importantly, I had a professional home inspector drop off a monitor and was able to validate this results of this device against a calibrated unit +/- 5%, close enough to call it perfect. For the cost, you can't beat it, I'd recommend testing this device with a calibrated unit to make sure. But once that's done it's invaluable, particularly in my case as I built a DIY radon abatement system (which worked in bringing my levels from 72pC/l to ~1). A python api is published as well, so I use a raspberry pi to pull readings and post them to a website so I can share my triumph against radon with friends.

Very simple to use and gave us the same readings as the test kits we had just used. This cost less than having someone come out and test for you. And, the beauty of this little gem, is I got to test my son's house too. We will be having remediation done on our house because of the high readings and it will be nice to check on the system installed to see if it works. Most new homes built these days are so tight in construction that it is almost impossible not to have high radon readings in many parts of the country.

Easy setup than other brands and priced fairly. Check it daily/weekly and feel it’s accurate against other radon testing levels.

During my home inspections prior to purchase my inspector found my radon levels elevated, so purchased this to monitor my levels prior to remediation. Turns out this device is very accurate in comparison to the two professional hired out tests that were preformed in my house. The device beyond plugging it in, and pairing their mobile app with the device over bluetooth it was up and running within minutes. Really love this and will continue to have it run all the time in my lower level to ensure my radon levels stay low also awesome I can get my reading from my phone. I love the graphs it produces as it stores all the data it gathers to show the long term averages of your radon numbers.

Easy to use. Wish I had known about this sooner. I was buying short term tests for $15 and paying shipping to the lab. With this I know my number daily.

Helped us monitor the radon level in our house. We were surprised how much the levels fluctuated. This monitor proved that we needed mitigation, and that the mitigation has been successful.

Without another accurate Radon detector with which to compare, it’s hard to tell how accurate this one is but the readings have been consistent since it was activated and it makes sense that the average is in the low 1’s in a newly constructed home built with radon barrier/exhaust. This device gets high marks for being easy to read and understand as well as being able to access it on the iPhone and iPad. I rated down one star on ease of use since the included instructions were unclear about which app to download for use - the third one I tried “RadonEye” (not Plus) was the correct version and it worked instantly once I used that.

Bought this device about a week ago with the aim of verifying that the radon levels in my 25 year old home were in the acceptable range. The home has a active radon mitigation system that was installed when the house was built. Radon levels at that time after installation were determined to be in the 2 pCi/l range. About 18 years ago we added a sunroom that has a crawl space connected to the main basement through a small access opening in the main basements wall. The construction of the crawl space is a poured concrete slab with cinder block walls with about 3 feet of headroom to the sunroom floor joists. After getting the RadonEye unit we tested the first floor and averaged a 24 hr reading of 1.5 pCi/l level with a peak of approx. 2 pCi/L. I was somewhat surprised by those levels. I moved the detector to finished part of the basement and obtained a 24 hr avg reading of 1.7 pCi/l and a peak of 2.5. I then moved the detector to just below the crawl space opening. The 24 hr avg was 5.6 with a peak of 7.5. That led me moving the detector around the unfinished basement confirming high levels in that part of the basement. I have now contacted a radon remediation company to address the crawl space radon problem. I only wish I had done this testing 18 years ago! But back then, the only available method was to hang carbon canisters around for 72 hours or more and then sending them out for analysis. I am very impressed by the RadonEye for its ease of use and the rapid information it provides. I have spoken to a number of my neighbors about this experience with the crawl space and for those who have added to their homes they too are very interested in following up to determine their radon levels.

I own 3 Radon monitors. The RadonEye, an Airthings Wave (2nd gen), and Corentium Home (also by Airthings). The Airthings monitors have had questionable accuracy over the past 11 months. The RadonEye has been much more accurate when comparing all 3 monitors to charcoal test results. That said, the most important thing about a Radon monitor is accuracy. I recommend this product based on accuracy alone. Additionally, I like that I can get a quick reading by looking at the small display on the device. The bluetooth sync functionality actually works fine between floors/walls, so lack of wifi connectivity hasn't been a problem. I love that you get your first accurate reading after only 1 hour with this monitor. The Airthings Wave takes a whole week to calibrate and they say to let it run for at least 30+ days to consider the readings accurate. I dock 1 star from the RadonEye for the following reasons though: - The app seems outdated aesthetically. When compared to the Airthings app and web dashboard it leaves a bit to be desired. - Learning how the RadonEye takes measurements can be a little confusing at first. It takes a reading every 10 minutes and then spits out an avg every hour. In the app these are called "data points" and graphed out as pci/l on the y axis and # data points on the x axis. I wish this graph was more of a time based graph, rather than showing how many data points you have and requiring you to do your own math to figure how long the monitor has been measuring, or the time a reading was taken based on those data points. - This isn't a very attractive device. Just a white cylinder with a screen on it. - I wish this had a longer power cable, or was battery operated. Being tethered to a wall socket limits the positioning of the monitor. Overall, despite my issues with the RadonEye, it's all about the accuracy in the end, and this thing has it. I recommend this product if you're in the market for a "smart" Radon monitor.

Wow. So easy to use, and I can’t believe I didn’t Buy this before now. A good way to check to see if the medication is working in your home. I am sharing this with friends and family.
