Reviews
Low cost option for power. Easy to install. It took maybe 30 minutes to put it on, connect to the app and to the Garmin head unit. Calibration is easy in both the app and head unit. Software updates quick with no issues. It seems like it might lag a touch here and there being a single side comparing it to my spider based units, but overall it works great.
Power meter works as designed. It allowed me to train using a garmin designed training. Easy to pair with Garmin watch and computer, and also with the 4iiii app. I can zero it if required but it has worked as designed. If I was not interested in training using power to improve my performance I would not bought it, however it provides all the necessary power training metrics that I need to improve my cycling performance, at a great and reasonable price.
Good accuracy, tremendous battery life and the piece of mind with Apple Find My. Assuming the battery life is as good as advertised it should last me about 2 years. I did end up putting in an Energizer lithium since the Panasonic battery that comes with it doesn�t seem to put out enough power, the connection to my Garmin kept getting dropped but has been fine since.
