I found no fault with it. The speaker is good for listening to music, movies or any videos, ok bass, very clear sound. The radio works- almost 6-8 channels are active in the worst signals. As for durability, takes abuse, but it's still been like a month or 2, so it's too early to make the call. Battery runs for like 2 hrs (used to be 4) at 20/30 volume. Let's see how it keeps. Overall great product.
