Ok, it's not got huge power but would be ideal for a kitchen/study/garage (if in range of course) or a small bedroom. Seems like a good bit of kit to me.
From the site;
Stereo wireless Bluetooth speaker
10 metre operation
10 watt power output
3.5 mm stereo line in jack
I'm guessing that it has a 3.5mm jack you could connect most other audio sources to this, I'm very tempted to get one of these to put in my gym for some workout tunes...
