Accurate with great features.

So far, I love all the features

Highly reccomend to petite triathletes (or any athlete) as it's feature packed, highly adjustable, and capable of tracking open water swims among other things like outdoor cycling, indoor, cycling, running, heart rate, and recommended recovery time

The features are great but the battery life of my device sucks

Tried all the handy tricks from Garmin..emailed Garmin support as to what I had tried only to have them email me back with the steps I had already tried.
