While that is true, I find that much more finicky. A phone or tablet with the Xert app always connects immediately and just works, with pc + ant or Bluetooth I always get hiccups or total failure.

I actually really like the Xert app for creating quick workouts, and it has very good trainer control. And then just watch a tv show rather than a Zwift world. I don't think you'll like the Xert modelling though..
