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.
I moved from Shimano Dura-ace SPD-SL pedals to these Garmin Vector 3's and was pleasantly surprised that the Garmin's feel just as solid as the Shimano pedals did. The difference obviously is that I can now read power via the pedals. Overall, the Garmin cleats work well and install basically the same as my old SPD-SLs.
If I had one negative to say about the pedals so far, it is that the seals on the bearings are a little tight, so the pedals don't spin as freely as my previous Shimano pedals. which means sometimes they are in a weird position when you clip in. I'm assuming these seals will loosen up after a few more months of training.
I bought a ton of batteries (They are cheap) in anticipation that I would need to change these out fairly often, but I'm up to 30 hours or so of riding and no need to change so far.
Overall, very happy with the Garmin pedals and they are super easy to install and move from bike to bike. That's going to be a big help for me later in the season when I move the pedals from my road bike to my time trial bike and back.
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.
