So far I could not find anything there wrong with this mini speaker. The sound quality is surprisingly good and the bass I am more than satisfied. Have ordered the product Thursday evening and Saturday lunchtime already knocked a friendly man from DHL on my door. Quick unpacked (been brief puzzled by the relatively large package for this small part), connected to the iPod and then I was able to play my favorite music. Can so far really only good to report about it and would the Wavemaster order immediately - just buy it!
