I wonder the sensor battery can only last a year even you don’t run frequently. I got 2 set a year and both sensors cannot be linked anymore. So frustrated since it’s one of my motivation to run. And I almost got a new set from Apple Online Store which costs HK$220, it’s quite expensive as I got 2 receivers at home have no use now!
Luckily I found Apple now selling the sensor alone HK$150.
Yes, you may say it’s still expensive and wonder why this little plastic can cost HK$150. Let’s think this way, you still save HK$70… =|
