    Used this to connect the 3 components of an MSpa jacuzzi to run from my phone after the board blew. Works brilliantly. The MSpa wiring diagram was actually wrong, showing the heater connecting only to live. Had to change wiring around a few times.

    Received very fast but not tested

    Excellent. Product received as described. Received before promised date. I’m very happy with both the product and service.
