Review on 🔧 Upgrade Your Ceiling Fan Control: Corebay Universal Universal Remote and Receiver Kit - Hampton Bay, Harbor Breeze, or Hunter Replacement, White - Easy Learning by Michael Keegan

The remote control manual was wonkey. It means moving the code switch to the down position and then pressing and holding the "Learn" button; Good that there is no code switch on the remote control. You will need a very small Phillips screwdriver to remove the screw that secures the remote's slide-out battery cover. Be sure to purchase separately and put a button cell battery (CR2032) in the remote control, otherwise it will not work. The Revain's description says it doesn't include a battery, but that's easy to miss. The rest of the device was easy to install and worked great.
