Negative Positive
Title: worked for 3-4 days
Review: I've had the radon detector for about a month. Didn't set it up right away--you know, quick shipping and then let it sit for a week or so. Anyway, initial reading of 2.5 corresponded well with my "send-in" kits. Then, "error message". Went through the manual to clear and reset. Then in a few days: "E,E,E,E", handbook silent on that one. Cleared OK, though. Then "8,8,8,8"--cleared OK. Then, "8.8.8.5"... That was today. Window to return to Amazon "closed 3/18". Have to get an RA number from the company and send it back "postage prepaid" (I think that means by me). Haven't had anything fail right out of the box in a long time. Hope this one is a fluke.
Is the review positive or negative?
