5 out of 5 eggsProduct Update

Pros: A correction to my previous review where I said the controller was turning on and off rapidly at the switching humidity. It turns out there is an option in the settings for a delay (1, 2, ... minutes). I set that to 1 minute and the unit is perfect now. I highly recommend this for a humidor.

Cons: None!

5 out of 5 eggsWorks Great

Pros: Used to control humidity in my self made humidor. Works just like it should.

Cons: Sometimes it will cycle the relay on and off a few times before deciding to stay off. Not a big deal really.

Other Thoughts: I would buy another one of these in a heartbeat. I made my own humidor humidification system for under $40 with the purchase of a 120V fan. I believe this controller is also made in a 12V version which would have actually been a better choice since small 12V fans are much cheaper.
