Bem Wireless speakerband: someone has already this accessory?

Hi,
this message is mostly for people living in the USA:
has someone of you already bought the Bem Wireless speakerband?
This accessory was presented last January at CES2014, and then was available for pre-order and finally came out to the public recently. It's a Bluetooth speaker which you can wear on your wrist as it is a watch, and you can play audio from it, connected via bluetooth to iDevices as usual.
In the description there is explained it has also music controls but i wonder if someone has it, and what does he/she think of it! You cannot buy it in Europe yet, so, before thinking of buying something that i can be unsatisfied of, i wish to hear some other users considerations
thanks for all!
