Xiaomi's new heart-monitoring band: not a fitbit-killer

Hot off the presses from China's biggest shopping day of the year: I present, a brand-new, just released Xiaomi Band with Heart Rate. It just went on sale on 11/11 at 0:00 midnight, and arrived in my hands at 9:15 AM. 

It is now 10:25 AM as I write this. 

The good: it looks exactly the same and functions very similarly to how the old band did. My expectation is that battery life will be similar. Cheap at 99 RMB = $15 USD. 

The bad: it doesn't do continuous heartrate monitoring, so I will still wear my fitbit charge HR on my left arm, and a xiaomi band on my right.
