Review: Highly recommend Ecosense RadonEye - This unit (RadonEye RD200) is very easy to setup, and gives you accurate results fast! Your first reading in 10 minutes and a very accurate reading after your first hour and every hour! It actually measures 30 times an hour and gives you detailed charts of all your readings in the app for your phone, and also displays the highest detected Radon level. I love that it shows the level of Radon on the unit itself too so if you are near it and just want to see what it says, it’s right there…no need for your phone or internet access, etc. You can see even more details on the app via Bluetooth so you can see your results on your phone without having to be right at the unit as well. Another huge benefit is that you can set it to alarm at any level, or not at all… (default is 4). I prefer to have it alert me if radon goes over 3. Most importantly it works accurately and fast! Other brands typical take 48 hours before your first reading and then don’t give you detailed results, but instead only give an average sample. They will still help, but this is much more detailed, fast and accurate all in one! The only thing I wish it had (with the detailed graph chart) was times of all the readings. It shows you all the levels, and the peak level and average level, but not what time they occurred. Other than that, I highly recommend this product!
Review: Great Product - Every homeowner needs for peace of mind - Live in a high radon area and failed old style charcoal canister test. Hoped I solved problem by finishing basement and installing vinyl sheeting behind the walls to stop air intrusion. Never retested until I read about about this radon detector in Times magazine review of top 100 new products of 2021. Readings in unfinished furnace area were consistent with earlier charcoal canister test. Reading in finished basement were cut in half but still over threshold for action. Will follow up with radon mediation contractors for estimates. What a GREAT product and I believe worth the much greater initial cost compared to mail in canister tests. You can easily make multiple tests over multiple days to see how readings fluctuate over time and quickly get results. It would cost more and take months to do this with the mail order tests. I have recorded the results from two day tests at different locations in my basement using the Ecosense app. This requires some renaming and storing of files using the app that maybe too complicated for some users since there are no step by step instructions provided. A simple alternative is to just record “screen shots” of the graphs and store them in your photos instead of on the app. I plan to redo the tests after remediation and use the before and after results to share with contractor as needed. I am also now doing similar tests throughout the first and second floors just to see if heating or air conditioning disperses radon gas throughout the house. This is the most extensive review I have ever written on desertcart. Since it really does impact your health and for anyone (like myself) who reads these reviews to try and make an informed decision, I want to pass along several other factors that impacted my positive review both before and after the purchase. I purchased this product instead of the slightly cheaper new model (EQ100 Cube) that was reviewed in the Times magazine article after reading desertcart reviews for that product. I liked the idea of not having the RD200 connected to the internet and not having results stored on-line with address information as in the EQ100. Some reviews of the RD200 from 2017 mentioned the need to provide average and peak values for the measurement interval, I was pleased to see that the manufacturer now provides this for the measurement interval. In addition, I was also concerned that I would only be able to store 1 years worth of data with the RD200 compared to 5 years with the EQ100. That is not really a limitation with the RD200 since you can delete the readings on the device after you have downloaded then to the app.

### ⭐⭐⭐⭐⭐ Lifesaving detector
*by T***C on January 1, 2018*

We bought a house and discovered we have a radon problem using a Corentium radon detector we bought on Amazon. It works fine, but only gives a near term reading and a 7 day average reading, and it takes a full day before giving results. Based on the Corentium detector we hired a radon mitigation contractor who installed the typical plumbing and fan, and using his own detector, he measured safe results and declared victory. Enter Radon Eye. We put this device in the living area where we would spend time, and quickly discovered that the levels were way above the readings the contractor had found. When we confronted him, we learned he had put his meter in a different location, and since we wanted all the rooms to be safe we had him do additional work, after which we put his detector side by side with our Radon Eye. Both produced the same results and we found that his work did not get the job done. We would have been exposed to very unsafe levels (over 20) if we had just trusted him the first time around. This is a reminder that “ignorance is NOT bliss”. He came back several times and tried different things, and none were successful. So after “investing” over $2000 in someone who was not an expert, we searched for and found someone who runs his own company and is an expert. Whereas our original contractor would send in his laborers and stop in occasionally to tell them what to do and then leave, the second gentleman spent half a day with us, discovered that the work done by the previous contractor was incomplete and totally inadequate, redid it, and now our radon levels are well within the safe range. Had it not been for our Radon Eye and the capability it provided to fully verify and document results, we would have been exposed for long periods to very unsafe radon levels. So, needless to say, we love our Radon Eye detector. It works perfectly, requires no attention or maintenance, and it gives a reading very quickly. Moreover, the graphical presentation in my phone or tablet makes it very easy to verify that the radon level is staying at safe levels. It is not a stretch to declare that this device has saved lives.
