The Graphite Facet Mini Jambox is my side kick. Overall a great device, but thats not what anyone cares about.So whats not so great:(note: this is really critical. The little things that could be better from a detail freak.)You can feel the base if you hold the device in your hands, but you can't really hear it.Usb input would be nice for charging other devices, even if the battery is only big enough for a little bluetooth speaker. Would be nice.There is customization of what buttons do, just not enough.Skipping tracks by double clicking the pause/play is not intuitive. Found myself constantly pressing the buttons to slow. A short press of the volume up and volume down would be preferred.Not a fan of the branding. Unsure of its purpose as it's almost impossible to read as is. To me the device is so unique it doesn't even need the minuscule JAWBONE branding.
