Got it. Don't like it.
The interface isn't bad, but it is inconsistent. Bluetooth connection to my Nexus 6P is also crappy - it keeps dropping and not wanting to reconnect. It does feel nice, but lacks the high-end feeling of the Moto360 or Huawei Watch.
The rotating bezel is interesting, but hard to grip as it is the same slippy plastic as the rest of the watch. And there are very few apps out at the moment.
