I've been running with Garmin for 8 years, and have loved every Garmin I've ever owned. That said, the 920xt is by far the best - Garmin has really outdone themselves here. GPS pickup is almost instantaneous. Small and light compared to my older FR 310xt and FR 305 (both brilliant in their own rights). Easy to use. Durable. And I love the wifi auto-upload when I'm at home or work. Bluetooth to my phone when I'm travelling. Simply brilliant!
