An important note here is it sounds much much better than a more expensive Bose Bluetooth speaker.

Bluetooth works flawlessly and it is solidly built

I bought this and the Aiwa Exos-9 Portable Bluetooth Speaker (https://www.amazon.com/gp/product/B00WF78GS4/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1),both about a month ago

:) nice bluetooth speaker~

Outstanding, the best portable Bluetooth speaker I ever own
