On advice from a DC Rainmaker review, I decided to add the Elite Sterzo Smart Steering block. Setup is stupid simple and I had zero issues. Zwift integrates well with steering block. It allows some steering choices, but you cannot run into other cyclists or take your own path off-road.
I am still on my original batteries after a few months and never turn it off. I believe it goes into a sleep mode when it senses it isn't being used. To use it, I just wiggle my handlebars and it connects within seconds.
The only criticism I have heard is sweat can short out the circuit board. I have dripped some sweat on top of the unit but not enough for it to run down through the holes in the top platform. I haven't experienced this issue yet. Until I can find fault, I'm giving 5 stars.
