Rather than buying an overpriced humidifier with a built-in humidistat that doesn't work, I opted for this. The built-in humidistat, NEVER works, and it's been my experience and that of others. Simply state, it is a poor engineering decision because the device can never get an accurate measurement of humidity if it is so close to the source, yet the stupid manufacturers keep on doing it, merely to jack up the price, and the end users have the common complaint of the humidifier having only two states: either on all the time or off all the time.
This one solves the problem. It comes out of the factory quite accurate. I checked it against a couple of hygrometers I trust, and when I placed them at exactly the same spot, the measurement of this device was spot on.
Couple of tips I give other users:
1) Relative humidity measurement can be affected significantly by the position of the measurement device in the room. That's not only because humidity distribution may not be uniform in the room, but more importantly because relative humidity depends largely on the temperature, and you'll have temperature differences between different spots in the room, especially in cold winter when you're heating the room. So, place the humidifier controller in an outlet as close as practical to the point where you want to regulate humiditiy, and definitely not close to your heater.
b) Given how sensitive the measurement is to temperature, be carefuly if you place the device against a cold wall. Again, very possible during winter, if the wall is not internal to the house, but rather a wall that separates your room from the outside. If this happens, then know that the device will be measuring relative humidity thinking that the temperature is actually lower than it is inside your room, which causes the humidity measurement to be higher than it should, it could cause the device to turn off the humidifer before the desired humidity is reached. If this placement is unavoidable, the solution is:
a. Plug the device where you want.
b. Give it a few minutes to stabilize and take an accurate read.
c. Compare its measurement against that of a hygrometer you trust that is placed at the point where you want to regulate humidity.
d. The difference in the reading between the two is a good rough estimate of the amount of correction you need to do when setting the humidifier controller. E.g. if your trusted hygro reads 35%, and this controller reads 42% (because it is placed at a non-ideal position), and you want to improve your humiditiy to 40%, then you set your controller to 47%.

Pros:
It works well. It keeps your plug-in humidifier or vaporizer running until the room humidity reaches whatever percent you set.
Cons:
-There is no way to calibrate it. However, this can be overcome by testing it and then adding or subtracting the difference when setting what humidity you want. On arrival mine was only a couple of percentage points higher than my properly calibrated hygrometer.
-It needs to be placed about half way up to the ceiling and away from anything producing heat in order to get a good reading.
