Had mine for over 1 month. Still not sure what value it presents. They just updated their Power Center and have added Running Stress Score, kinda like Strava's Suffer Score.
Not sure if I gain anything compared to just running with heart rate. After seeing DCRainmaker's video where he did some fast solid running- he had his power readings between 300-400! Sadly at 73, the highest I got mine was around 225. Have yet to really hammer with it, but most of the time I run around 11:00 minutes per mile which measures around 170. Wireless battery recharge works ok. I get around 18-20 hours of running before it starts to flicker a light advising it has about 10% battery left.
Interested if any members are using the device and has it been beneficial?
Thanks. Nick
