Summary: It doesn't last long enough. The batteries die fast even when they are turned off! I don't know why. They sound ok for little speakers but they just don't hold the charge that I needed them to.
Summary: These speakers have proven to be reliable and long lasting we have been using one for over a year and it just keeps on going. The battery life is longer than my mp3 plus the sound is clear and loud depending on volume and well worth the price. Keep in mind outdoors these will do just fine for a small group, more than 20 people then buy something bigger enormously bigger.
Summary: These are perfect for listening to ones ipod songs "outloud" rather than through ones earbuds. There are a few wires to deal with and I am not crazy about the magnets but these speakers serve the purpose I bought them for!
