Inconspicuous (I wear a watch on my other hand and want it to look like a strap)
Lasts a few days
Excellent companion app
Accurate altimeter (correctly measures the floors climbed)
An exercise that has been turned on often terminates itself incorrectly and unexpectedly (birth pain - I assume the FITBIT programmers will quickly solve it)
Measuring oxygen in the blood - it has a sensor, but its use is still pretty useless
The heart rate measurement is quite accurate during prolonged activity, but the bracelet takes an awfully long time to figure out that the heart rate is increasing. If I run up the stairs for two minutes, I have a real heart rate of maybe 150. But the bracelet only registers a heart rate rise to about 80. Same thing on the treadmill, where I can see the heart rate on the display. The Charge 2 was already behaving like this, so maybe it's a tax for low consumption and I have to accept it.
