This unit works great allowing me to link the Zwift desktop app to my TacX Smart Trainer. I recently discovered that in addition to this, when I start an 'indoor ride' on my Garmin Forerunner 735xt, I can also connect my heart rate monitor to my Zwift desktop app, but it doesn't show up as the watch's name, instead it is displayed as "Heart Rate Belt #####". There is a slight lag as you increase cadence/power, but it's no worse than the lag you might experience when using the mobile app. I highly recommend this very affordable Ant+ device.
