Clicks when wind blows
I like this fan now that I am used to the humidity sensor....but there is a flap at the venting connection that clicks back and forth when the wind blows. It drives me bonkers - so I'll have to see what type of material I can put around the edges to stop the clicking.

Awesome Humidity Sense Bath Vent Fan
Bought one of these units eight years ago and still going strong. Yes, one has to select auto sense (Blue LED) or flip the switch for manual (orange LED). However, the auto sense works great and tapers down to barely turning if not enough humidity. It works far better than a humidity sensing switch because it does detect the last remnants of humidity high in the ceiling. As another purchaser also pointed out the blue light makes a nice night light and the fan is quiet. We have never walked into ...

Auto Humidity Control feature
For a competitive price you get a fan with an auto mode for humidity control. It appears to be well made.

Great for 2 Years! Humidity sensing no more!
We purchased this in 2021 and it worked great up until the past two months. It seems the humidity sensor is no longer properly activating the fan. The fan barely comes on during a ten minute hot shower leading to a sauna like bathroom unless one remembers to flip the switch to manual mode prior to getting in the shower. Great unit when it was working, now not so much.

No more humidity
This is the fifth time I’ve installed this fan and love these things. Terrible at remembering to turn the fan on? It does it for you!
