Inkbird is a reputable company like boatguy posted. My dehuey has its own humidity controller, so I use my inkbird for my humidifier. I have however used it for my smaller dehueys, but it works just fine. For some reason, the inkbird humidity controller from Amazon is different from the one on ebay,, and they look exactly rhe same. The one on ebay actually has a temp guage. You can't control the temp with it, but pressing both the up and down buttons together flashes the temp for a few seconds which I found pretty cool.
