never received it and also lost the dispute.
I thought I could use each separate relay, and latch them with 2 transmitter buttons. WRONG!!!!! You can only latch with the relay's - not with the buttons. If you are latching, it only gives 2CH (2x2 relay) If you toggle, it gives 4CH (4x1 relay) So i had to change my strategy, and i worked it out........
