The speaker is doing what he should and functioning properly - Coupling with my phone (Galaxy S2 Android 4.0) was done in seconds and works smoothly. Even the repeated switching between headphones / headset / speakers to the mobile phone does not cause coupling problems. Range with Bluetooth operation seems to be very good, the sound quality is perfect, no noise etc.
In this respect, the speaker would actually 5 points deserve - but unfortunately suffers the sound quality of the relatively small design. In direct comparison with the MOBI Wavemaster this drops significantly, the sound sounds thin, nearly tinny (Before someone asks: Of course I've extended the speaker, in the collapsed condition, the sound is completely useless).
I considered briefly to keep the speaker anyway, and a MOBI to get stuck in the "BuddyPlug" socket - what works beautifully and produces a great sound - but as an overall solution is the whole then being evil expensive.
Here one must therefore consider:
If you want absolutely the convenience of Bluetooth connectivity instead of tangled cables and can make compromises in sound quality, then this is a great device - who does not know the MOBI, should be quite satisfied with the RAIKKO - he is clearly better than the mobile phone speaker anyway.
If you want to enjoy music or sound better used, then I can only advise.
