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!

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.

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.

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.

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.

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.

I am working as engineer in development of similar products (alarms and indoor climate rcontrol). Last year I bought product of Airthings because my house is located in an area with pretty huge of the radon activity. So I have more one year experiency with this product. It is good product for end user. It gives good and easy read out information. If you are not pushing for fast results this product gives you information what you buy for. But my expectations are little bit higher and I need faster information to be able to recognize in few steps where is radon source and base on this to do some measures to mittigate this. I have levels in my house within 100-400Bq in living part of my house and also above 1000Bg in pillar and other technic rooms located underground. Fortunately there are no hallway between and these spaces are separated by a radon insultion. Depends on wheater conditions is possible to measure level as 5000Bq (!!!) it is temporary but in coherence with weather. So why I am writing about - because this product fulfill my expectations well and it is really able to find a source of problems. I also did some easy comparations with Airthings product and have to say that results are fully within my expectations. First feeling was the same in plenty of commnets giving low ratng for this product, but after long period observation the results are comaprable. Is necessary to take into consideration that these products (both of mentioned) are consumer electronics not equipments for a laboratory or scientific measurements. In this price level it could be sign as one of the best products. In comaprison with Airthing there would be fine to do some improvement. But also Airthings App has its own cons e.g. graphs readibility for weak eyes (my case). One technic information at the end of my quite long assesment (sorry for that). The physical principle of radon activity detection says that the bigger detection chamber the better and faster results are. Radon Eye has few times bigger chamber in comparisson with not only with Airthings but maybe among of all in this level of comparable end user oriented products.

When I moved into my house, the Radon inspection found an elevated level of ~4.0. We had it professionally remediated, and though I always had considered buying one of these at some point *just to be sure*, it was hard to justify the expense. Many years later, I decided it was time. I bought this brand and one from another popular Amazon company. Man, was I glad I did! First — a word about the product. I prefer this detector. The other (Airthings) is meant to be more accurate per the reviews, but they were almost identical in their read-outs, but this one lets you access the collection data via a Bluetooth so you can see the fluctuations in radon (it tends to go up overnight) and get a really nice picture for the trend using (for me) my iPhone. The other one did not have Bluetooth, and though it has long and short term data, it doesn’t allow you easy access to the trend with individual readings, as does Radon Eye with its iPhone App. In the main area where I believe the original test was, I was getting an average score of 3.5. Not crazy, but worth further investigation. (The fact that this still considered abnormally high but isn’t the punchline if this review should give you a sense of what is about to happen) Since this puppy is quite portable, I moved it to another area of my basement where I have a sewer clean-out valve with some exposed dirt. In this second location, the count went up to 40-60 on average, going up to 80 at the highest!! I immediately contacted the remediation company and had it addressed and now I’m down to 0.5 average no matter where I put it. Don’t wait. It’s worth the money. Don’t trust it to the remediation companies and wherever they arbitrarily place the test kit. If I hadn’t been able to move it around my basement for real-time readings (sorta — it collects data every 10 minutes or so), I never would have found the crazy high Radon leak in my basement.
