Teacher: Now, understand the problem? Solve this instance: I was excited to discover this item on closeout sale. The unit lasted not 3 hours before it failed. To begin, the banana plug for the iPhone was a sloppy fit and required jiggling it around to make it work and if the phone was moved it lost connection - frustrating. Then the left speaker lost about half of it's volume. I couldn't get it back, so I returned the unit the next day. Total time of usage - about 1 1/2 hours.
