Im so sad that i bought any Polar products. I can believe how hard and unintuitive the products are. I bought everything. the computer m460, v2 watch, the cadence and the wheel speed sensors. all of this cost me money and cant believe how unhappy i am about this purchase. even the videos telling you how to sync everything is 4 years old and this video does not even tell you how to get cadence to display on the computer or watch. Just how to pair it.
