Our Review

Overall, I enjoy this watch.  I've used other tracking watches and haven't been that impressed with the functions.  This is an overall good watch that I have used in triathlons and enjoy having my own real-time transition and discipline time.    Positives
  • Tracks multisport, including transitions, with one push of a button
  • Quick view of current speed and time within discipline
  • Smart Notification lets you receive emails, texts and alerts right on your watch (Iphone connectivity only)
Okay With
  • On the swim, I noticed that it will add an extra 25-50 yards that I didn't actually swim.  Just be mindful of any extra flicks of arms, such as drinking water bottle or reaching for kick board/buoy.
  • Price is a bit higher than some on the market, but the fact that it will change between yards/meters, miles/kilometers is a plus that outweighs the price (along with the other positives listed here).
  • Difficulty Bluetooth connecting for syncing - this isn't a dealbreaker as it very may well be partially user error
  • Very large for a female wrist but does not get in the way.
