2 RadonEye Pro for sale

I have 2 RadonEye Pros for sale. Bought less than a year ago and will need to be calibrated March 2023. I have only used these a handful of times. I dont know why these are not more popular than they are. These have great reports and are easy to set up. Looking to get $400 each. You pay shipping from Billings, MT.
