Based on your hunt I ordered this and received it tonight. my first Zwift experience was difficult. The resistance just wasn't working. After an hour or so of fumbling around it turned out it was paired incorrectly to the pc. I had to pair the trainer to the FE-C option then I heard the resistance motor kick in. prior to that I was spinning out 50x34 120 rpm and showing 200 watts.... after pairing correctly it was spot on.
