Although initially this sensor seems light and comfortable, the edges prove hurtful and body movements with this model cut my chest after 30 minutes of running. Adhesive tape can be used to limit the problem, but it's honestly not practice and Forgetting, we are left until the skin lacerated even bleed.
Heursement I have no problem in cycling and the sensor works well.
But Mr Garmin, please test your product and review your copy, my skin will thank you.
