Review on Enhanced Smart Ceiling Fan Control by Martin Jerry: New, 4-Level Speed Control, Alexa & Google Home Voice Control, SmartLife App Integration, Requires Neutral Wires, Supports 2.4G WiFi Only by Curtis Kincade

We've been Martin Jerry fans (pun intended) for years, especially their smart light switches. Recently we've been looking for a smart switch that works with ceiling fans. We tried another brand of dinner switches, but the fan made a whirring noise when turned off (ours is a 4-speed Hampton Bay). So we searched the internet and found this switch. Setup was easy and works great. All 4 speeds work as expected and the fan doesn't hum. It's also easy to set up on Google Home. Definitely recommend.
