This jar is such a cool idea and the speaker sounds pretty good considering it's attached to the bottom of the jar, but the jar I received has a loose piece of metal that sealed in the cup. Every time I pick up a cup and tilt it to drink, you can hear the metal sliding inside, which is REALLY annoying given that it's absolutely impossible to get it out. When you shake the cup, it looks like a rattle.
