Amazing sound (only on fw 0.4.3)
The good:
Sound quality is the best I've heard (but only on firmware 0.4.3, apparently after that they changed the sound and it's more close to their competition, not too good and not too bad)
Build quality
Portability
The bad:
You have to manually change the firmware
The latency is not very good for movies (you can always adjust a delay but it's not plug and play)

Best audio experience of my life!
I have nothing to say other than that this box delivers the best possible sound for the price and portability, I'm using Oluv's version 0.43 and the difference between the 0.50 is huge, look for a tutorial on YouTube!

Best value for money
Clear sound and long lasting battery. There is all you need from tiny little speaker. The only cons is difficult to see buttons at low light. Thanks!
