At first, the $199 pricepoint seemed high, but it seems to be a cross platform high end fitness tracker with basic smartwatch functionality. Incidentally, this puts the price point right in-between FitBits and Android Wear watches (and also the iWatch).

Furthermore, 2 day battery life is a very welcome addition. I wouldn't mind putting one of these on my wrist.

The price actually seems low to me. The built in GPS and HRM make it compete with higher end endurance watches that cost $300+. I'm considering dumping my TomTom Multi-Sport Cardio for this if the real time stats during running are good enough.

My problem is that if it's also a sleep tracker. When are you supposed to charge these things?

1.5 hrs to full charge, 30 min to 80% charge. I'd charge it while making breakfast.

>30 min to 80% charge

That's impressive. But why does it take 60 minutes to charge the last 20%?

To put it really simply: Batteries are nonlinear. Charge/discharge rates vary based on the current amount of power stored in the battery.

That makes a lot of sense, thanks.
