The WILLHI WH1436H Works great and was available here for about the lowest price I have found. Good value.I built a humidifier myself with a large plastic tub and a House of Hydro 5 head Head Water Fogger and tested it for 3 days. After it seemed to be working great I ordered this WILLHI WH1436H control unit to automate it.The WILLHI WH1436H control unit sensor is sensitive, breath on it and the humidity jumps up quickly and then settles back to where it was quickly.Setup was super easy.Durability... I have only had it for a week or so, under the circumstances I can't comment on durability yet.I have a 3000 sq ft 2 story house and it now stays at 50% down stairs where I keep the humidifier and 48% humidity upstairs. Before is was in the low to mid 30% range.UPDATE - it has now been 5 and a half months and this unit is still working perfect. Based on that and the other details above, I can recommend it.~

I'm using this with a room humidifier and it does the job keeping the humidity within a range. My main complaint is that even though the manual states the control has been simplified it's still too complicated in my opinion. In particular, if you press the wrong button you can easily enter some obscure settings that are difficult to figure out without reading the manual. In this case the easiest way out is to reset the control and start over.Another issue is that the humidity probe at the end of the cable is not the most aesthetic to have in your bedroom. It's a black thing that looks like it belongs in a lab or factory.I have one more issue with this controller. Once programmed in auto mode I would like to be able to chose the initial state on or off. It should have a button to toggle this but it does not. The way I got around it is I blow a hairdryer on low heat on the probe to lower the humidity and for it to switch into on state.

I like that this product is easy to set up. Plug and play. Part of the reason I bought this was because of the glowing reviews it received, and because I've seen some people I follow use it in their grows.Buyer beware though! If you're trying to dial in your environment so you can set it and forget it, do not use this equipment! I see why it's so inexpensive because the parts in the sensor are not made with quality. My sensor worked fine for about a week and then it stopped working correctly. It would not read the RH correctly, and so it never shut off my humidifier. I couldn't make it home that day and just watched my rh levels go crazy (after I had clearly set the setting to go off at a lower rh). Needles to say, I will not be purchasing anything from this company again. I saw a review that was similar to my experience and thought, "I'm sure I'll be fine...he probably just got a lemon." Smh.

I use this device to regulate humidity in my mushroom grow tent. It has made my humidity control easy and consistent. I liked it so well that I bought a second unit for my second tent. Highly recommended.

Perfect for a diy fruiting chamber . I like that it has a replacable sensor .

This humidity sensor/controller is pretty easy to set-up and program. However, I've only used it for 1 month and already one of the RH sensors doesn't work anymore...good thing it came with two sensors.

LOVE this user-friendly humidity controller! Just set it & walk away. Makes life a lot easier.

Set up in a cold room in a bar to control mould. Works with exhaust fan plugged into humiditySensor.set trigger level at + 75%.

works, no issues.

Worked like a charm for the two months, and now as I'm a few days passed the warranty (bought 3 November 2020 and the support stop 5 February 2021), the controller won't stop even pass the humidity level. I have to shut it down for a few hours before it work okay and then the problem show up again. I use it to control the humidity in my house via a system I built, it's a huge problem as when I come back to home or wake up the morning in a fog apartment like if I was in a bar in the '90!
