AI Review Summary:

Overall sentiment is positive. Buyers say the sensor reliably detects humidity spikes and prevents fogging and mildew, with many reporting easier installs thanks to interchangeable line/load and the option to wire without a neutral. Programming and setting adjustments are praised as straightforward by some, but a recurring complaint is that configuration isn’t intuitive for everyone and can require re-reading instructions. Performance is generally consistent across multiple bathrooms and fans, and value is viewed as strong for automating ventilation. Representative quotes: “Works perfectly—fan kicks on right after a shower.” “Install was simple in an older home without a neutral.” “Settings are a bit confusing at first but fine once dialed in.”
