I first thought it might be used because of the scratches on the control panel. My wife & I both l examined it to see if it had a protective plastic covering but did not see any edges. Emailed TK to complain - They responded almost immediately to ensure the unit did indeed have a protective covering over the control surface. We looked again and it did indeed have a barely perceptible clear plastic covering - Unit was flawless. It came with a hands-free headset mic, charger, shoulder-strap, and carrying case. The quality of the speaker is amazing! Whether the input is voice, mp3, or FM, it is clear and crisp at any volume...And believe me, this unit will project at LOT of volume. It comes fully charged and provides 10+ continuous hours per charge. My born-again Friends and I will use it for outdoor evangelizing and look forward to drawing a crowd to hear the Gospel of God's Grace; the message of Salvation which comes through repenting of our sins and placing our faith in Jesus Christ alone as Lord & Savior...And to God be the Glory! Review: Solid Product for Me - Works great and to boot it has an input where you can hook up your MP3 player to speak for you if you're not up task. I use it for open air preaching the Gospel of Jesus Christ. It holds a charge for a long time and sounds really clear for the most part. The amplifier is a sliding bazooka style with a low profile that hangs over one shoulder and rests on your opposite hip.The headset is just OK because it is kind of short and you need to position it it just right. It still works really good, but it just could be better in my opinion. I may decide to get a sleeker headset that is of a smaller profile as well. Either way, it's well worth the price. I recommend this one over all the others out there under the $300 price point. ## Features - POWERFUL VOICE AMPLIFIER – This portable speaker delivers 25W of amplified sound, covering 8,000 sq ft making it ideal for public speaking, fitness classes, or any situation that requires a reliable communication device.
