      • great features, questionable life

      I've been putting these in my rentals over the years as appreciate the feature set to protect my tenants. That being said, these appear to be designed to have a 5yr lifespan, plus or minus a year, and they start to consistently fail. I would normally have no issue with this if it was a reasonable limit on detector, but clearly it is not (I'd expect 10-15yrs). Once you understand this, can figure out for yourself what the real value is. The feature set is excellent, the lifespan not so much.
