Familiarity: I've put it through the wringer
Bought the Garmin Vector 3S from CC and started using them late last year. Put about 2,500 miles on them so far. Love them but had to change the batteries pretty much right away. I have learned that the thing to watch out for is the correct pedal torque spec and using good batteries when setting up the pedals. After I starting using them, they worked until the batteries went low after about 300 miles. Replaced the batteries and initially the pedals did not pair and read right; spikes and inconsistent numbers. Took them off the bike and re-installed them again with the recommended torque, and no more problems. They are paired with an older Garmin 500.
