Rock solid and capable of throwing the bike around during a sprint, or climbing an incline on Zwift. The Smart Control version is a better value for just a little more money, especially if you are using Zwift.
Honestly speaking I am not a fan of indoor riding but decided to add this bad boy to my arsenal. After logging maybe just a couple hundred miles I can tell this Kinetik trainer exceeded my expectations. The ability to swing is a game changer as it really makes you feel free on a bike.
I must mention that had some problems with connecting my Garmin hear rate monitor but honestly was too lazy to read FAQ or manual to solve the problem. I am sure its an easy fix.
Summary quality, usability, design is on the top level.
