Tried and online cheaper manufacturer for this and it would continue to fail. Decided to go with a reputable brand which has been outstanding from the second I plugged it in.
The dongle works as advertised. When analyzing the Zwift log file using the Zwiftalyser web page. I am experiencing ~10% Rx dropouts. No sure if the dropouts are caused by the distance from the trainer, the trainer itself or the dongle. I suspect dongle is not responsible but I can't be sure without trying a different dongle which I have not done.
