portability

awkward to switch on power

Nice easy to use portable speaker. Ideal for watchings movies on ipod and mp4 players.

No too loud. Some bass tones are muffled.

No good points.

Quite simply it didn't work. It was tried on several different models of MP3. I told them about this and tried to get a response from them for about 3 weeks and they just kept ignoring me. They never replied.
