1.Before you buy, please send your serial name - like EVGC0652012080587 (on the back of the controller) to firstname.lastname@example.org
to confirm if the receiver is compatible with your ESM-9101 controller.
2.Check out the video we made for you to see if your ESM-9101 controller Logo lights are blinking like in this video. https://bit.ly/3Os7Mih
If not,the dongle will not work and cannot be connected to your controller, so don't buy it. ---This is very important!
3.If you still keep your old/broken dongle, you can also take it apart to see if it is the same as the picture we took, if not, it is not usable.
