works perfect so far - no drop outs .
To be honest I don't have any other power measurement devise to compare these to, all I can say is they work and add more cycling dynamics to look over.
Very easy to use and provides great data as a training tool
The Garmin Vector 3 Power Pedals function exactly as expected and are very accurate.
I use this on my indoor smart trainer. I like the Garmin Cycling Dynamics information
For $1000 pedals, I shouldn't have to put mineral oil on batteries to ensure they make a connection. Really disappointed.
