I've got one this year and no problems. I did not have to set anything up, it just worked out of the box. I did however get the scales [jing- same as yours] and the display from the same supplier on Banggood. Could be yours aren't compatible.

Jes,

You should have had the book, tell him through Ebay it's an incomplete order.

I have a friend who is renowned for seeking the keenest price. He bought a readout and scales direct from China but separate suppliers.

Physically compatible but the plnouts on the scales were different to those required by the readout, even though the plugs fitted. He persevered. Rewired the plugs and got it all working.

Given the separate suppliers, he hardly had grounds to reject either. Me, I'd rather get the whole setup from the same supplier even at a somewhat higher cost.

Not saying this applies to the OP, just something else to be aware of.
