I have the LED mask and the cord / USB insert broke over time so I wanted to replace that without buying the whole product over again and to my appreciation you did have the replacement control module available and it works great. Thanks
Sadly after buying the new control unit I found it hasn't made the mask work, it just turns on and straight off so all parts are redundant now. Never mind, I did so love that mask though, it made a big and positive difference to my complexion.
Thanks for asking.
