Review on Effortless Control: Revolutionize with 🎛️ Switch Wireless Control 1 Channel Transmitters by Jason Lockwood

Part 1: Overview of what I just received: I checked if the plastic on the batteries in the transmitters needs to be removed. Both batteries in each transmitter were included. Yes, there are two batteries in each transmitter. This part is NOT clear in the instructions or OEM advertising. In addition, the instructions contain a disclaimer: the installer must be an electrician. Part 2: UPDATED (20190805) The attached image shows there is not enough space for the cable connections when using the "black" case. In addition, you need to understand the concepts of cathode and anode to install the R121A correctly. If you plan to use only one remote control, you can remove the batteries from the second remote control to extend battery life. Part 3: UPDATED (20190807) A power indicator is attached to the receiver board. The power indicator and the other "signal" indicator that is also attached to the board are a waste of time as you normally can't see either indicator as the case covers both indicators. Star rating changed from 3 to 4 due to overall quality and "easy" installation. Part 4: (TBA) After weeks of durability assessment.
