I have a set of the Withings ones – although I’m a Garmin user I went with these over the Garmin ones because their v1 scales apparently had firmware and wifi issues, and the newer ones weren’t out.
The withings ones have been very good – support multiple profiles and their app is fairly good for tracking data. They will sync weight into Garmin connect via MyFitnesspal which works well most of the time – but it’s just weight, none of the body composition stats. It will also push weight into Strava, which should then push it to Zwift but that can be a bit flaky.
Buying today, if it looked like the issues had been fixed with the new Garmin scales, I’d probably choose those.
