Question Sony SmartBand fitness/activity/life tracker

Hey all just wondering if anyone here has purchased the Sony SmartBand yet? I'm contemplating getting one but already have the Withings Pulse activity tracker and a Sony SmartWatch 2.
I'm a fan of Sony products but not sure if the SmartBand is worth getting.

For those who don't know what the SmartBand is take a look here
