Right now, the only time I have to align my sensor to the magnets is when I change the sensor battery.
The only time I've ever had magnet alignment issues is when I've kicked the s/c sensor with my heel. You're right, battery changes too. Transport my bike in the car
a lot. It's just never been an issue.
I got rid of the sensor when I got a power meter, and use GPS for speed. At the end of the day if the ride distance is off by 50 feet per mile it won't affect anything.
