This was unbelievably accurate. My house was tested for Radon a month ago with a reading of 2.01 by a lab- this device registers 2.0 to 1.97 to 1.67 throughout the day, so it's very close to the lab tested amount. The plastic feels a bit on the flimsy side, but shouldn't matter too much since it'll just sit on a table or shelf. I'm withholding a star for the fact that this can't be connected to anything smart - no integration. So you have to go in person to see the reading. I have it in the far part of my basement. Would've been great if it had some sort of integration to Home Assistant, or SmartThings or even a simple web ui. I guess that adds a lot of complexity to a simple device, so it wasn't an option. The accuracy earns this all it's stars. Bonus is that it's USB-C, not micro-usb... AND it comes with plug and cable.

When we bought our house 3 years ago, a radon test was required. The level came back at 8pCi/L, so a mitigation system was installed. It pains me to think about the previous family that lived here for almost 20 years and having no idea what the radon level might have been and knowing how easy it would be to assume it will remain low. This product is pricey, you could do a yearly mail-in test for 10 years for this price. And it doesn't have wifi or an app like some other products in this price range. I don't care so much about that, but other people might, and this does collect lots of data that could have been useful to view in another manner. This is mostly why I'm taking off the one star. However, this feels like a quality product. It looks and is packaged like a nice consumer electronic, not any kind of industrial equipment, and comes with everything you need to use it including a power block. You could easily display this anywhere and it looks like a cute little clock. It could not have been easier to use - open the box, plug it in, and you start getting real time readings shortly after. The instructions say to place it 20" from the floor or any walls. The floor is easy, any counter or shelf works, but 20" from the wall may not always be possible - not sure how that affects readings, but we'll see as I move it around the house. There's only two buttons, one to change the readout (real time, various averages) and one to change settings (brightness, units). I'm a little torn on not having an app to view the data, but I do love the simplicity of not having to set anything up or having to download anything. The only other hesitation I have about this is that I'm not sure how you'd confirm that it is or remains accurate. The instructions I think say the accuracy is +/-0.7 pCi/L, which may be fine generally but seems a little large when the safe level is 2.

I’ve been looking for a device to monitor my radon levels at my new house. I’m hoping that I can verify that we don’t have any issues. I had it professionally tested before we purchased it. The levels I’m reading fall into line with what I had seen at inspection. I had a high alert the first day but I’m wondering if it was false as it went from 1 to 4(high) really fast after about 2 hours. It has multiple settings(Day, Week, Month) to see an average over the modal time. This is a nice peace of mind. I’ll keep checking it periodically.

This radon monitor could not be easier to use. Take it out of the box and plug it in. Once powered up, it reads the radon level every 10 minutes. Using the push-button on the back will cycle through the various reading averages with every push - real time, daily, weekly, monthly, and long term. Real time - updates every 10 minutes with the latest reading Daily - updates every hour with the last 24 hours of moving average Weekly - updates every 24 hours with the last 7 days of moving average Monthly - updates every 24 hours with the last 30 days of moving average Long term - updates every 24 hours with total days averaged since monitoring began In our case, the alarm went off within a few hours of plugging it in. The alarm defaults to alert when the radon level read is over 4 pCi/L (the EPA recommended level to mitigate), though you can adjust between 2 pCi/L to 5 pCi/L. Our readings range between 1 pCi/L to 10 pCi/L at various times and locations within the house so we are now looking to find a reputable and knowledgeable mitigator. To better diagnose our particular problem prior to paying someone to monitor, assess, and bid the job, I subsequently also purchased the EcoQube, which logs readings every 10 minutes. Their smartphone app allows viewing the logged readings as well as viewing averages by day, week, month, and year. Additionally you can export the data for your own data manipulation. I find this to be better suited for diagnosis purposes since I can place it any room for 24 hours and see the graph of every reading over a 24 hour period (or more). The EcoBlu is fine on its own for long term monitoring either if you don't have a radon problem, or after mitigation when you want to monitor the efficacy of your mitigation system. I prefer the EcoQube for diagnostics efforts with its ability to offer a finer granularity to the readings and downgraded the EchoBlu 1 star for that reason.

When I originally got the device, I thought I was getting a battery powered one. Since then, the vendor made it clear in the product description that it is not. Aside from the cube-shaped monitor, the product comes with a stand and a USB-C cable and 110v power adapter. Setup was a breeze: just take the items out of the box, clip the stand onto the cube, and plug the device in. Less than 60 seconds. In just a few minutes, I got my first Radon reading. Nice! But because it's not battery operated, it's hard to find a good place for this Radon monitor. While this white cube isn't offensive looking, the black cable does look ugly when the device sits on a book case or coffee table. And those furniture items have to be near a power outlet. And the user guide says the monitor must be at least 20" from a wall and 20" off the ground. Not easy to fulfill all those requirements - and nearly impossible to hide that ugly cable! I asked the vendor about the silliness of not having this be powered by batteries - as are my VOC monitor and my temp/humidity monitor. The vendor said that accurate and frequent monitoring would take too much power, so they had to decide on accuracy vs. portability. Not sure why Radon monitoring would take more power than VOC monitoring - and my VOC monitor also needs to send its data via wifi to my HomeKit app, whereas this monitor doesn't even have wifi. Anyway, if you have agood place to put this monitor, I highly recommend it. If you're like me and don't like ugly cables staring in your face - especially for something you only occasionally look at - you might be better off looking for a wireless radon monitor. I deducted one star for it not being wireless because that's what I thought I was getting.

Got this to do monitoring in an older home. It's very easy to use, just plug it in and it starts working. I don't know yet how accurate it is. I've just sent off a conventional short term test to the lab so we'll see how the results compare to what this detector is reporting. Pros: Very easy to setup and use Clear instructions Cons: None yet. If I needed another detector to have in another location I would buy another one, assuming that the accuracy is confirmed by lab test results of a conventional short term Radon test kit. But in reality it is easy to move this to different locations in the home for testing, so other than for convenience you probably don't need more than one of these detectors.
