I have the first generation of this trainer, the Drivo 1. A friend plugged in a 24v power supply into my Drivo which requires 12v and damaged the control board. Elite support helped me get a replacement board in a very timely manner. This for a trainer that has been out of warranty for 3 years. So if you are looking at a smart trainer you should consider what support will be available after the warranty period. My Drivo is now back online and performing perfectly.
