I LOVE these speakers. I have had them for two and a half years and used them many times. They have worked perfectly at a surprising distance away from the house, outdoors, and indoors. They are just good enough for parties where you want background music. Not really loud or bassy enough for a loud dance party, but they have plenty of bass and volume for average use, and are more than adequate -in fact perfect- for the kind of party where conversation, eating and drinking predominate. They look cool and the infrared remote control is a nice touch which works very well. The fact they are splashproof is a bonus when our English weather decides to spoil a day time garden party -no panic to save them, they can look after themselves up to a point.
I have mine permanently set up in my kitchen, where they run off the mains, but they work very well off batteries anywhere else.
They are excellent value and a great product.
