Non-essential but nice,
Verified Purchase(What's this?)
This review is from: Polar 2013 Wearlink Nike+ Transmitter Set (Sports)
Links just fine with Nike+ SportWatch GPS Powered by TomTom (Black/Volt) as well as the cardio equipment in my local gym (and can talk to both at the same time). Seems accurate enough, or at least self-consistent (I have no way to cross-check, but displayed BPM agrees with my sense of level-of-effort, and is consistent across runs). I don't think it's revolutionized my training or anything, but it's another piece of data and the graphs are pretty (the elevation profile of a run, alongside heartrate and pace, gives you a pretty good story of how your workout went).
Be aware that this will *not* communicate with the Nike+ app on smart phones; don't let the branding mislead you, the sensors only talk to the watch.
The band doesn't really feel constricting when running; wetting it before each run is a bit of a hassle but not as cold as I'd worried it would be (and sweat handles it after that). In a little over a month of running with it, I've had the latch pop open once - it was raining pretty heavily that day, and my shirt might have been dragging against it, but I wouldn't want that to happen if I was wearing this in a race. Otherwise, it's been easy to attach, has always linked immediately with the watch, and basically no problems.
