When I got mine I stuck to the Wattbike Hub, I find that better for actual workouts. But the Zwift environment is more fun once you get into it. I just wish there were more options of where to ride, the French routes are really nice but seem to be unavailable most of the time.
Oh god the steering update, nearly had me quit. I couldn't see anyone else. Totally on my own for 3 TDZ events. Turns out it was because I was disabling the broken steering on the initial pairing screen and not leaving it alone. People are still complaining their team/others can't see them but as long as you leave the buttons alone (to avoid going round in circles) it does seem to work. Also if you unpair once riding it seems ok. Stupid update, badly conceived, both companies have been rubbish at communication over it. Had to scream at them on Twitter to get any help.
But, when it works its great and I think the Wattbike is an incredible tool. Give us a follow if you like, look for "Holdroyd". My other half is finding it hard to get comfortable on it. We have to swap seats which is a pain.
BTW I have updated to beta firmware on Wattbike Hub and now on to a new stable release. Do make sure yours is up to date. I'm using a iPad Air 3. If you're on a laptop then it seems many say to use ANT+ instead of Bluetooth.
