Herbert D.wrote a review of Garmin Vector 3 Power Meter Pedals on August 4, 2019
Familiarity: I've put it through the wringer
First, I CAN NOT recommend these pedals as a finished product the right sensor does not really record data (read full review below).
I purchased the Garmin Vector 3 (both pedals) in May 2019. For the first 2 weeks everything was great. I ride 3-4 times a week, 30- 60 miles at a time. Connecting the powermeter is easy. Using the garminconnect app with the powermeter is great. After the second week I noticed the warning 'Right power sensor missing' would come up during my rides. I thought it was the batter, so I replaced the battery in the both pedal (very easy to do). The warning persisted. I did research online and found this was a known issue from the launch of the product. The design of the right battery compartment cause the right power sensor to loose connection. I contacting Garmin, free of charge they sent me a replacement battery housing for both pedals (easy to install). Then everything was fine for another 2 weeks, then back to 'right power sensor missing'. That is were I am now. I think there are other fixes that can remedy the problem, but the end user should have to 'DIY' finished products to make them work. I CAN NOT recommend these pedals as powermeters, the data capture is unreliable. I don't know how long the right sensor connection is missing before I get the warning. But I do have the Garmin Vector 2 pedals, and they are awesome. I can definitely recommend the Garmin Vector 2 pedals.
