Rechargeable Battery, Compact size, Two straps (small and large)
Cons:
Smaller Display (vs. 201), no HRM (vs. 305), no real effective Battery indicator
I love this device. It's been nothing but reliable, and has gotten me through an entire year of running without sign of letting up. The battery stays charged for several runs, although there isn't a great way to tell how much battery you have left.
Other models have better bike integration, and even HRM capabilities, but for the money, this device is a great value. There is a feature for multisport detection based on speed, but I have never used the feature because I prefer to just rely on my conventional cycometer.
