I compared these to the original Antself Stick and they are definitely different. First, I noticed that this one has a few more dropouts and connection issues compared to Ant itself. Second, the reason for putting the star is that if you want to send ant+ (as opposed to the standard receive signal for zwift etc) it will NOT send it because the firmware won't allow it. This is a known issue that unfortunately hasn't been fixed, but will work for 99 percent of the population.
