I initially loved the sound the speaker put out but the USB port kept falling into the speaker and I would get a replacement...fast forward 5 replacements later the USB port seems to have gotten fixed BUT the speaker sounds blown :(
not to mention battery issues with a battery that is non-replaceable in the unit
I give up!
New company to try I found was Photive with their CYREN speaker - I ordered it from a site I do surveys on to get free stuff (Click here if you're interested)
Let me tell you right out the box the port feels solid- the sound is AMAZING, and so far I haven't had any issues with it sounding like blown speakers.
In my opinion Photive CYREN wins over Native Union- Sorry Native Union, you need to make your equipment better!
