Very good product! I have both boxes "Raikko Vacuum" and "Wave Master Mobi" tested. In advance I can tell, both systems are their Worth money. There are differences but of course. Both a very good sound quality (in terms of size), where the Mobi cuts slightly better. When maximum volume overhauled the Vacuum the Mobi really clear! As well as in battery life. When it comes to Raikko stimulated 10 hours been on high volume. When Wavemaster 3. The rest was I personally less important. They both look chic, where the taste decides. I kept the Raikko because he delivers a good sound, and the volume much much higher than the Mobi.
