It's the perfect blend of SmartWatch and Smart Volume.
And moreover, it has a few handy extras.
Speakerphones, and not like a normal headset. Whether you make a call using the Smart band decides where one answers the call.
Voice commands. One can ask the band what time it is, what the weather is or will be, where the mobile phone is (mobile phone will ring), set alarms, calendar entries, or learn how much% battery the phone didnt. All by voice.
There are in my view only one shortcoming. The handsfree in the car now has to be always connected manually.
I can really recommend the swr30. The price may seem a bit steep. But if you have a bunch of stuff "outsource" wants, and you want to read a message discreetly times, this band is just right.
