I've been using this speaker with an i-pod for large family events and parties and it can be easily heard in large halls above nattering parents and excited kids! It's light weight and very portable. The mic input is very useful with separate control from the master volume. On the whole the sound quality is good but not fantastic, and it distorts a bit on songs with a heavy bass. This can be rectified by turning the bass down temporarily but then gives a 'tinny' sound. If your priority is a reasonable sound, high volume, versatility and portability within a budget then buy it. If your priority is a high quality sound then maybe it's not the speaker for you - try the Mackie at a much higher price. On the whole I'm very pleased with it.
